It is a pictorial representation in solving a system.
-
Analytical
-
Polygon
-
Graphical
-
Mathematical
Correct Answer
A. GraphicalExplanation
The correct answer is "Graphical" because a pictorial representation is often referred to as a graph. In this context, the graph is used to solve a system, which suggests that the solution is being represented visually rather than analytically or mathematically. A polygon is a shape with straight sides, and while it can be used in graphical representations, it is not specific to solving a system. Therefore, "Graphical" is the most appropriate answer.Rate this question:

Galvanized steel are steel product coated with
-
Zinc
-
Iron
-
Silicon
-
Boron
Correct Answer
A. ZincExplanation
Galvanized steel refers to steel products that have been coated with zinc. This coating provides protection against corrosion and rust, making the steel more durable and long-lasting. Zinc is chosen for this purpose because it has excellent corrosion resistance properties and forms a protective barrier on the surface of the steel. This helps to prevent the steel from coming into direct contact with moisture and other elements that can cause it to deteriorate over time.Rate this question:

Some members in the truss which cannot carry load
-
Two force member
-
One force member
-
Force member
-
Zero force member
Correct Answer
A. Zero force memberExplanation
A zero force member in a truss is a member that does not carry any load. This means that there is no force acting on the member, and it does not contribute to the stability or strength of the truss structure. Zero force members are typically found in trusses where the loads are applied at the joints, and they help to maintain the equilibrium of the forces in the truss.Rate this question:

By departmentalization of an organization, it decentralizes __________.
-
Authority
-
Responsibility
-
Accountability
-
All of the above
Correct Answer
A. All of the aboveExplanation
Departmentalization of an organization involves dividing the organization into different departments or units based on various factors such as function, product, geography, or customer. This decentralization of authority, responsibility, and accountability allows for greater autonomy and decision-making power at the departmental level. By distributing these elements across different departments, the organization can effectively delegate authority, assign responsibilities, and hold individuals or teams accountable for their actions and outcomes. Therefore, all of the above options - authority, responsibility, and accountability - are decentralized through departmentalization.Rate this question:

The general law of mechanics that stress is directly proportional to strain
-
Hooke’s law
-
Boyle’s law
-
Shearing stress
-
Elasticity
Correct Answer
A. Hooke’s lawExplanation
Hooke's law states that the stress applied to a solid material is directly proportional to the strain produced in the material. In other words, when a force is applied to a material, it will deform or stretch in proportion to the force applied. This law is commonly used to describe the behavior of elastic materials, such as springs, where the deformation is reversible and the material returns to its original shape when the force is removed. Therefore, Hooke's law is the correct answer because it directly relates stress and strain, as stated in the question.Rate this question:

The tension in the cable is the same on both sides of the pulley.
-
Gravity
-
Frictionless pulley
-
Pulley
-
Friction
Correct Answer
A. Frictionless pulleyExplanation
The tension in a cable is the same on both sides of a frictionless pulley because there's no resistance at the pulley to alter the force. A frictionless pulley allows the rope or cable to move smoothly over it without any energy loss, meaning the force (tension) remains equal on both sides. If the pulley had friction, it would affect the tension, making it unequal on either side.Rate this question:
