11
A lever is best described as:
✓ Answer:BA rigid bar capable of rotating about a fixed point
A lever is a rigid bar that rotates about a fixed point called the fulcrum. Hence, B.
12
If a machine has mechanical advantage equal to 1, it:
✓ Answer:CProduces the same force ideally as the applied effort
MA = Load/Effort. If MA = 1, then Load = Effort for an ideal machine. Hence, option C.
13
The fixed point about which a lever rotates is called:
✓ Answer:CFulcrum
The pivot or fixed point of a lever is the fulcrum.
14
Which statement about a simple machine is correct?
✓ Answer:CIt can make a task more convenient
Machines make tasks more convenient by changing force, direction, or speed. They do not create energy or violate conservation of energy.
15
The distance between the fulcrum and the point where effort is applied is called:
✓ Answer:BEffort arm
The effort arm is the perpendicular distance from the fulcrum to the line of action of the effort.
16
For an ideal machine, which relation is correct?
✓ Answer:AInput work = output work
Ignoring friction, conservation of energy gives input work = output work.
17
The distance between the fulcrum and the load is called:
✓ Answer:BLoad arm
The load arm is the distance from the fulcrum to the line of action of the load.
18
A machine allows a small effort to lift a large load. Which quantity is generally greater than 1?
✓ Answer:AMechanical advantage
If a smaller effort lifts a larger load, Load/Effort > 1. Therefore, mechanical advantage is greater than 1.
19
In a first-class lever, the arrangement is:
✓ Answer:CFulcrum between effort and load
In a first-class lever, the fulcrum lies between the effort and load. Scissors and seesaws are examples.
20
Which factor makes a real machine less efficient than an ideal machine?
✓ Answer:BFriction
Friction converts part of the input mechanical energy into heat and other forms, reducing useful output work.
