### Q1 To prevent vehicle roll during cornering the roll center has to be:

• A.

At 2/3 of the vehicle CoG height

• B.

At the level of the vehicle CoG

• C.

At 1/3 of the unsprung mass CoG height

• D.

At the level of the sprung mass CoG

• E.

• F.

D. At the level of the sprung mass CoG
Explanation
The correct answer is at the level of the sprung mass CoG. The roll center is the point around which the vehicle body tends to roll during cornering. Placing the roll center at the level of the sprung mass CoG helps to minimize body roll and maintain stability during cornering. This is because it allows the suspension to work more effectively in controlling the vehicle's body movements. If the roll center is not at the level of the sprung mass CoG, it can lead to excessive body roll and reduced stability.

### With "Pro-Ackermann" Steering the steering angle is bigger on the outer wheel.

• A.

True

• B.

False

• C.

Not related with the steering handle

• D.

Option 4

B. False
Explanation
The statement is false because with "Pro-Ackermann" Steering, the steering angle is actually bigger on the inner wheel, not the outer wheel. This steering mechanism is designed to improve the turning radius of a vehicle by allowing the inner wheel to turn at a sharper angle than the outer wheel, reducing tire scrubbing and improving maneuverability.

• C.

25.4cmX15cm

• D.

D. 20cmX10cm
Explanation
The correct answer is 20cmX10cm. This is the area of the technical inspection sticker that should be left on the upper nose of the vehicle.

### How many D.O.R is there in a proper suspension system assembly in a formula student car.

• A.

5

• B.

Sufficient to restrain in a particular direction

• C.

1

• D.

4

B. Sufficient to restrain in a particular direction
Explanation
The correct answer is 1. In a proper suspension system assembly in a formula student car, there is typically only one D.O.R (Degree of Rotation) that is sufficient to restrain the movement of the suspension in a particular direction. This ensures stability and control of the car during racing or driving conditions.

### Identify the type of milling cutter shown in the figure above

• A.

Slot drill

• B.

End mill

• C.

Side and face cutter

• D.

Shell end mill cutter

D. Shell end mill cutter
Explanation
The milling cutter shown in the figure above is a shell end mill cutter. This type of cutter has a cylindrical shape with cutting teeth on the periphery and on one end. It is designed for removing material from the surface of a workpiece in a milling machine. The shell end mill cutter is commonly used for creating flat surfaces, slots, and pockets in metalworking applications.

### Tensile stress is a stress that acts...

• A.

Parallel to the surface

• B.

Along the surface

• C.

Perpendicular to the surface

• D.

Against the shortening of an object

• E.

Against the lengthening of an object

C. Perpendicular to the surface
Explanation
Tensile stress is a type of stress that occurs when a force is applied perpendicular to the surface of an object. This stress tends to stretch or lengthen the object, causing it to deform. Therefore, the correct answer is "against the lengthening of an object."

### What will Young's Modulus be for a 20 mm square bar and with a length of  600mm when it lengthens by 0.5 mm under a load of 45 kN?

• A.

135 GPa

• B.

180GPa

• C.

315GPa

• D.

515GPa

A. 135 GPa
Explanation
Young's Modulus is a measure of the stiffness of a material and is defined as the ratio of stress to strain. In this question, a 20 mm square bar with a length of 600 mm lengthens by 0.5 mm under a load of 45 kN. To calculate Young's Modulus, we can use the formula: stress = force/area and strain = change in length/original length. Rearranging the formula for Young's Modulus, we get: Young's Modulus = stress/strain. Plugging in the given values, we find that Young's Modulus is equal to 135 GPa.

### Which one of the following classifications of turbine is used for internal combustion engine applications?

• A.

Turbocharger

• B.

Root blower

• C.

Centrifugal blower

• D.

None of these

• E.

All of the above 3

E. All of the above 3
Explanation
The correct answer is "all of the above 3". This means that all three options mentioned (turbocharger, root blower, and centrifugal blower) are classifications of turbines used for internal combustion engine applications.

### What describes the delay between the time when a slip angle is introduced and when the cornering force reaches its steady-state value in a pneumatic tire.

• A.

Contact patch

• B.

Relaxation length

• C.

Slip ratio

• D.

B. Relaxation length
Explanation
The relaxation length describes the delay between the time when a slip angle is introduced and when the cornering force reaches its steady-state value in a pneumatic tire. It represents the distance over which the tire gradually transitions from an initial slip angle to a steady-state slip angle. This delay is due to the tire's viscoelastic properties and the time it takes for the tire to deform and generate the necessary cornering force. The relaxation length is an important factor in understanding the tire's handling characteristics and its ability to maintain grip during cornering.

### The above graph gives the relation between distance and digitized voltage. 1 / (d + k) = a * ADC + b where d - distance in centimeters. k - corrective constant (fund using tial-and-error method) ADC - digitalized value of voltage. a - linear member (value is determined by the trend line equation) b - free member(value is determined by the trend line equation) CALCULATE THE DISTANCE FOR GIVEN VALUE OF ADC = 100V AND K= 2.

• A.

625 mm

• B.

71.2 cm

• C.

0.637 m

• D.

55cm

C. 0.637 m
Explanation
The given equation relates the distance in centimeters (d) to the digitalized value of voltage (ADC) and a corrective constant (k). To calculate the distance for a given value of ADC = 100V and k = 2, we can substitute these values into the equation and solve for d. The result is 0.637 m.

### When the BSPD triggers a fault, and later is rectified. To reset, you :

• A.

Press the reset button

• B.

Power cycle the TSMS

• C.

Power cycle the GLVMS

• D.

None of the above

C. Power cycle the GLVMS
Explanation
To reset the BSPD after it triggers a fault and is later rectified, you need to power cycle the GLVMS. This means turning off the power to the GLVMS and then turning it back on again. This action will reset the system and clear any faults that were previously triggered. Pressing the reset button or power cycling the TSMS are not the correct methods to reset the BSPD in this situation.

### Locate the center of gravity of the volume generated by revolving the shaded area about the z axis. The material is homogeneous.

• A.

Z=2.8ft

• B.

Z=2.7ft

• C.

Z=3ft

• D.

Z=2.67ft

D. Z=2.67ft
Explanation
The correct answer is Z=2.67ft. The center of gravity of a volume generated by revolving a shaded area about the z-axis is located at the average value of the z-coordinates of all the points within the volume. Since the material is homogeneous, the density is constant throughout the volume, and the center of gravity is not affected by the shape or size of the shaded area. Therefore, the center of gravity is located at Z=2.67ft, which is the average of the given z-coordinates.
