A load of 600 N is lifted by an ideal lever with MA = 3. The required effort is:
✓ Answer:B200 N
MA = Load/Effort, so Effort = Load/MA = 600/3 = 200 N.
32
The main advantage of a single fixed pulley is that it:
✓ Answer:BChanges the direction of effort
The free end can be pulled downward while the load moves upward, making the task more convenient.
33
Which arrangement combines fixed and movable pulleys?
✓ Answer:ABlock and tackle
A block-and-tackle system uses multiple pulleys, often combining fixed and movable pulleys to obtain greater mechanical advantage.
34
Which simple machine is most directly associated with a threaded fastener?
✓ Answer:AScrew
A threaded fastener is based on the screw principle.
35
For an ideal lever, if the effort arm is twice the load arm, the mechanical advantage is:
✓ Answer:C2
MA = effort arm/load arm = 2/1 = 2.
36
A movable pulley is used mainly to:
✓ Answer:BProvide mechanical advantage and reduce required effort
A movable pulley can support a load with more than one segment of rope, reducing the effort required.
37
If the number of supporting rope segments is increased in an ideal pulley system, the required effort for the same load generally:
✓ Answer:BDecreases
More supporting rope segments share the load, so the required effort decreases in an ideal system.
38
The velocity ratio of a machine is 4. If the load moves 0.5 m, the effort moves:
✓ Answer:C2 m
VR = distance moved by effort/distance moved by load. Therefore dE = 4 × 0.5 = 2 m.
39
A 300 N load is 0.2 m from the fulcrum. The effort is applied 0.6 m from the fulcrum. For balance, effort is:
✓ Answer:B100 N
Using the principle of moments: Effort × effort arm = Load × load arm. E × 0.6 = 300 × 0.2 = 60, so E = 100 N.
40
For an ideal single movable pulley, the mechanical advantage is generally:
✓ Answer:C2
A single movable pulley is supported by two rope segments, so ideal MA = 2.
