Which lever class has the fulcrum between the load and effort?
✓ Answer:AClass I
The fulcrum lies between effort and load in a first-class lever.
72
In an ideal pulley system, if the load moves upward by 1 m and the velocity ratio is 3, the effort moves:
✓ Answer:D3 m
Velocity ratio = distance moved by effort/distance moved by load. Therefore effort distance = 3 × 1 = 3 m.
73
A doorknob is a common example of:
✓ Answer:AWheel and axle
A doorknob is a wheel-and-axle arrangement: turning the larger knob produces rotation of the smaller axle.
74
A lever has MA = 4 and lifts a 800 N load. The effort is:
✓ Answer:B100 N
E = L/MA = 800/4 = 200 N.
75
Which quantity is the ratio of distance moved by effort to distance moved by load?
✓ Answer:BVelocity ratio
Velocity ratio (VR) = distance moved by effort / distance moved by load.
76
Which simple machine is commonly used in a jar lid?
✓ Answer:AScrew
The helical thread on a jar lid forms a screw mechanism, converting rotation into controlled linear movement.
77
Why do scissors cut better when the object is placed close to the pivot?
✓ Answer:AThe load arm becomes smaller
For a given effort, the required load force can increase when the load is closer to the fulcrum because the load arm is smaller.
78
An ideal machine has MA = 5 and VR = 5. Its efficiency is:
✓ Answer:C100%
Efficiency = (MA/VR) × 100 = (5/5) × 100 = 100%.
79
A staircase mainly acts like:
✓ Answer:AAn inclined plane
A staircase provides a longer path to gain height gradually, similar to an inclined plane.
80
A pulley is essentially:
✓ Answer:AA grooved wheel used with a rope or belt
A pulley is a wheel with a groove that guides a rope. It can change the direction or magnitude of force.
