A wedge is essentially made by combining:
✓ Answer:ATwo inclined planes
A wedge can be considered as two inclined planes joined together. It is used for cutting, splitting or separating materials.
62
If a lever is balanced, which equation is correct?
✓ Answer:ALoad × load arm = Effort × effort arm
For rotational equilibrium, clockwise moment equals anticlockwise moment: L × load arm = E × effort arm.
63
Which machine is commonly used with pulleys to lift heavy loads at construction sites?
✓ Answer:ACrane
Cranes use pulley arrangements to lift and move heavy loads efficiently.
64
A screw can be regarded as:
✓ Answer:AAn inclined plane wrapped around a cylinder
The thread of a screw is an inclined plane wrapped helically around a cylinder.
65
Which lever class generally has the load between the fulcrum and effort?
✓ Answer:BClass II
The load is between fulcrum and effort in a second-class lever.
66
If a real pulley requires 250 N effort to lift a 500 N load, its mechanical advantage is:
✓ Answer:C2
MA = 500/250 = 2.
67
Which simple machine is commonly used in a knife?
✓ Answer:AWedge
A knife has a sharp wedge-shaped edge that concentrates force over a small area and helps cut material.
68
Which lever class generally has the effort between the fulcrum and load?
✓ Answer:CClass III
The effort is between fulcrum and load in a third-class lever.
69
A fixed pulley does NOT ideally:
✓ Answer:DMultiply the load force
A fixed pulley has ideal MA = 1, so it does not multiply force.
70
A wheelbarrow is an example of a combination of:
✓ Answer:ALever and wheel-and-axle
A wheelbarrow uses a second-class lever arrangement and a wheel-and-axle at the wheel.
