Mechanical Aptitude Test Questions With Correct Answers

Mechanical Aptitude Test How can the applied force required in order to lift a load be calculated? - Answer- F = W/N F = applied force by the user. W = weight of the load. N = number of load-supporting ropes. How can the gear ratio be calculated? - Answer- Gear ratio = N1/N2 = V2/V1 How can the length of the rope pulled in a compound pulley be calculated? - Answer- L = DxN L = length of the rope pulled. D = vertical distance of the load lifted. N = number of load-supporting ropes. How can the velocity of meshed cogwheels be calculated? - Answer- N1(number of teeth in wheel 1) x V1(Velocity of wheel 1) = N2(number of teeth in wheel 1) x V2(Velocity of wheel 2) How do moveable pulleys provide a mechanical advantage? - Answer- The rope wrapped around the pulley pulls the pulley upward twice, with each part of the rope. Since the tension is balanced along the entire rope, the weight is divided equally. When using a moveable pulley, the ceiling carries half of the load. How is torque calculated? - Answer- Torque is calculated as the product of the force applied onto the body (for example the weight of a load) and its distance from the hinge or pivot. If the system has an even number of cogwheels, ... - Answer- ... the last cogwheel will turn in the opposite direction to the first wheel. if the system has an odd number of cogwheels, ... - Answer- ... the last wheel will turn in the same direction as the first wheel. In a series circuit, the current is ... - Answer- ... identical through all components. The difference in electric potential between two points is called: - Answer- Voltage The hydrostatic pressure (the pressure of standing water) depends only on ... - Answer- ... the height of water column above the measurement point. The rate at which electric energy is transferred by an electric circuit is defined as: - Answer- Electric Power The velocity of each cogwheel in a system ... - Answer- ... can be calculated using data from every other cogwheel in the system. The velocity of meshed cogwheels ... - Answer- ... is proportional to the number of teeth What are common examples of 1st class levers? - Answer- A pair of scissors, a scale, a shelf with an anchor.
