Answer 1

Solution :-

MA is the abberiviation of Mechanical advantage

Mechanical Advantage = Load of body/Effort of the body

Mechanical Advantage = 7400/370

Mechanical Advantage = 740/37

Mechanical Advantage = 20/1

Mechanical Advantage = 20

Now

Efficiency = (Mechanical Advantage/Velocity) × 100

Efficiency = (20/20) × 100

Efficiency = 1 × 100

Efficiency = 100

Hence

Mechanical advantage is 20

Efficieny is 100
