Detailed Solution

Muscular force comes from muscles in living beings, while mechanical force comes from machines or tools.

Muscular force: Humans and animals apply it using muscles. It is a contact force. It depends on health, training, and fatigue. Examples: lifting a box, pedaling a bicycle, a bull pulling a cart.
Mechanical force: Generated by devices using energy sources like electricity, fuel, wind, or water. It can be larger and more uniform than human effort. Examples: a motor lifting an elevator, a hydraulic press shaping metal, a windmill turning blades.

Aspect	Muscular force	Mechanical force
Source	Biological muscles	Machines and mechanisms
Control	By nervous system	By switches, valves, programs
Consistency	Varies with fatigue	Stable and repeatable
Scale	Limited	Can be very large
Examples	Lifting, pushing	Motors, gears, hydraulics

In many tasks we combine both: a worker guides a power tool, or a farmer steers a tractor. Understanding the difference helps choose the right tool for safety and efficiency.
