Fs Austria Quiz 3

The dynamic event maximum score distribution for FSA is 100 points for Efficiency, 75 points for skid pad, 325 points for endurance, 100 points for autocross, and 75 points for acceleration.

The distance Y to the centroidal axis XX of the beam's cross-sectional area is 91.7mm.

If a bent tube is used in the primary structure, an additional tube must be attached to support it. The attachment point should be along the tube where it deviates farthest from a straight line connecting both ends. This is because the point of maximum deviation is where the bent tube is most vulnerable and needs additional support to maintain structural integrity. Attaching the additional tube at this point will provide the necessary reinforcement and ensure the overall strength of the structure.

The question states that the fastest team took 22 minutes to finish the event, while your team took 30 minutes. According to the rules, the score is calculated based on the time taken, where the faster the team, the higher the score. Since your team took longer than the fastest team, your score would be lower. Therefore, the approximate score obtained by your team in the event would be 0.

The correct answer is v^2/2μg,v/μg. This is because the shortest distance required to stop the block can be calculated using the equation d = v^2/2μg, where d is the distance, v is the velocity, μ is the coefficient of friction, and g is the acceleration due to gravity. Similarly, the shortest time required to stop the block can be calculated using the equation t = v/μg, where t is the time. Therefore, the correct answer is v^2/2μg,v/μg.

The correct formula for calculating longitudinal load transfer in a race car is wX(a/g)X(h/l). This formula takes into account the weight of the car (w), the longitudinal acceleration (a), the height of the center of gravity from the ground (h), and the wheelbase (l). The division of h by l in the formula indicates that the load transfer is dependent on the ratio of the height of the center of gravity to the wheelbase. This makes sense as a higher center of gravity or a longer wheelbase would result in a greater load transfer during acceleration.

When the instantaneous centre (IC) is inboard, the camber change rate will be higher. This is because when the IC is inboard, the distance between the IC and the wheel is smaller. As the wheel moves up and down, this smaller distance causes a greater change in the camber angle. On the other hand, when the IC is outboard, the larger distance between the IC and the wheel leads to a smaller change in the camber angle. Therefore, the positioning of the IC affects the camber change rate.

When the roll center is above the center of gravity, the body leans into the corner while cornering. This happens because the roll center acts as a pivot point for the body's lateral movement. With the roll center above the center of gravity, the body tends to rotate around the roll center, causing it to lean into the corner. This is a common phenomenon in vehicles with a higher center of gravity, such as SUVs or trucks, where the body tends to sway towards the inside of the turn.

The minimum Factor of Safety (FOS) can be calculated by dividing the ultimate strength of the material by the working stress. However, the question does not provide the ultimate strength of the material. Therefore, it is not possible to determine the correct answer or provide an explanation.

The Brake Specific Fuel Consumption (BSFC) rate of an engine is a measure of the fuel efficiency of the engine. It is defined as the amount of fuel consumed per unit of power produced by the engine. In this case, the fuel consumed is given as 150kg/hr. To calculate the power produced by the engine, we need to know the mean effective pressure (MEP) developed in each cylinder. The MEP is given as 12 bar. Using the formula for power, which is the product of MEP, cylinder volume, and number of strokes per minute, we can calculate the power produced by each cylinder. Then, by multiplying the power produced by the number of cylinders and dividing it by the fuel consumed, we can find the BSFC rate. The correct answer is 0.27kg/kw-hr.

The given equation is (X/tan42) = {(3X+4)SIN80}/COS140. To solve for X, we can start by simplifying the equation. Using the values of sin80° and cos140° (which are approximately 0.984 and -0.939, respectively), we can rewrite the equation as X/(0.900) = {(3X+4)(0.984)}/(-0.939). Simplifying further, we get X = -0.939(0.900)(3X+4)/0.984. Solving for X, we find that X is approximately 1.034.
