An inclined plane is:
✓ Answer:AA sloping surface used to raise or lower objects
An inclined plane is a sloping surface that allows a load to be raised through a smaller effort over a longer distance.
42
A machine has MA = 2 and VR = 5. Its efficiency is:
✓ Answer:B40%
Efficiency = (MA/VR) × 100 = (2/5) × 100 = 40%.
43
Why is a heavy object easier to lift when the effort arm of a lever is increased?
✓ Answer:BA larger turning moment is produced for the same effort
Moment = force × perpendicular distance. Increasing the effort arm increases the turning moment for the same effort.
44
A 400 N load is lifted by an ideal single movable pulley. Required effort is:
✓ Answer:B200 N
With ideal MA = 2, E = L/MA = 400/2 = 200 N.
45
The main advantage of an inclined plane is that it:
✓ Answer:BReduces the force required by increasing the distance over which it acts
A ramp reduces the required force compared with lifting vertically, but the object travels a longer distance.
46
A machine has efficiency 75% and VR = 4. Its mechanical advantage is:
