If the weight of the object is 30 kg, how much force is required to lift the object?

Question: If the weight of the object is 30 kg, how much force is required to lift the object?



Solution:
• Given:
Weight of Object (W) = 30 kg
Gravitational Acceleration (g) = 9.81 m/s²
Number of Ropes Supporting the Load = 1

Calculation of the the Weight Force (Load):
Weight Force = Mass × Gravity
Weight Force=Mass × Gravity = 30 × 9.81 =30 × 9.81 = 294.3 N = 294.3 N

Determination of the Mechanical Advantage (MA):
Since there is only one rope supporting the load, the mechanical advantage is:
MA = 1

Calculation of the Required Force:
Effort Force= MA/Load Force
= 1/294.3
= 294.3 N

The required force to lift the object is 294.3 N (approximately 294 N).

Since this is a single fixed pulley, it only changes the direction of force but does not reduce the effort needed.
