Question

What is the mechanical advantage, if a load of 1000 kg is lifted by a simple machine and effort applied is 250 kg? .​

Answer 1

Answer:

Mechanical advantage=Load/effort

Load=1000kg

Effort=250kg

M=1000/250

M=4.

Answer 2

Concept:

• The mechanical advantage
• The force amplified by utilising a tool, mechanical device, or machine system is known as a mechanical advantage.
• To achieve the desired output force amplification, the gadget trades off input forces against movement.
• The law of the lever serves as a paradigm for this.
• Calculating a mechanical advantage involves determining how much force is amplified by the mechanical system.
• It provides the ratio of the force needed to overcome the supplied force to the force provided to the load.
• Since the force is represented by the two ratio quantities, the equation has no units.
• Another definition of mechanical advantage is the force that a machine produces when a force is applied to it.

Given:

• Load = 1000 kg
• Effort = 250 kg

Find:

• Mechanical advantage

Solution:

We know that mechanical advantage is the ratio of load to the effort

Mechanical advantage = 1000/250 = 4

The mechanical advantage is 4.
