Question

The ratio of the load to the effort is called.
A Mechanical advantage
B Velocity ratio
C Efficiency of machine
D None

Answer 1

Hint: To solve this question we can say that according to Sir Isaac Newton, the force of an entity equals its mass, multiplied by acceleration. This basic principle is what is used to calculate load force, which is the force that opposes that entity. The object's mass is the resistance acted upon its load force. Mechanical Load, in mechanics, is the physical stress on a mechanical system or component. Loads can be static or dynamic. Some loads are specified as part of the design criteria of a mechanical system.

Complete step by step answerRatio of load to the effort is the mechanical advantage of a machine. The ratio of the velocity of effort to its velocity of the load is called the velocity ratio (VR) of that machine. The ratio of the load to the effort is called the actual mechanical advantage of the machine. The VR of a machine is the ratio of the distance moved by the effort to the distance moved by the load. If a machine had no losses, then the efficiency would be 100% (MA=VR).

Therefore, the correct answer is Option B.

Note: It can be said that load is a heavy or a bulky object that requires effort to move or lift the load. Effort is an applied force to bring desired change to the position (push or lift) of the load. The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted. The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it's energy production or machine efficiency.
