Start practicing Simple Machine RRB PYQs and strengthen your Railway Physics preparation.
1
If the effort is doubled while the load remains constant, the mechanical advantage:
✓ Answer:BBecomes half
MA = Load/Effort. If effort doubles for the same load, MA becomes half.
2
What is the primary purpose of a simple machine?
✓ Answer:BTo make a task easier by changing the magnitude or direction of force
A simple machine does not create energy. It helps us perform a task by changing the magnitude or direction of the applied force. Therefore, option B is correct.
3
A machine has a load of 900 N and an effort of 300 N. Its MA is:
✓ Answer:B3
MA = 900/300 = 3. Thus the machine multiplies the effort by a factor of 3.
4
The force applied to a machine is called:
✓ Answer:BEffort
The force supplied by the user or external agent to operate a machine is called effort. Hence, option B is correct.
5
Which statement is true for a real machine?
✓ Answer:CSome input energy is lost due to friction
Real machines experience friction and other losses, so some input energy is converted into heat, sound, etc.
6
The force that a machine has to overcome is called:
✓ Answer:BLoad
The resisting force or force that must be lifted/moved is called the load. Hence, option B is correct.
7
A simple machine may allow a person to use a smaller force by:
✓ Answer:BIncreasing the distance through which the effort acts
Force reduction is normally accompanied by a greater distance moved by the effort. This is the force-distance trade-off.
8
Mechanical advantage of a machine is defined as:
✓ Answer:BLoad/Effort
Mechanical advantage tells how many times the machine multiplies the applied force. Therefore, MA = Load/Effort.
9
Which principle is fundamentally obeyed by simple machines?
✓ Answer:AConservation of energy
Simple machines obey conservation of energy. They cannot give more energy out than is supplied.
10
A machine lifts a 600 N load with an effort of 150 N. Its mechanical advantage is:
✓ Answer:C4
MA = Load/Effort = 600/150 = 4. Thus, option C is correct.
