The study of non-moving bodies under known loads, how forces affect static bodies is called?

A.

Dynamics
B.

Strength of materials
C.

Statics
D.

Kinematics

Correct Answer
C. Statics

Explanation
Statics is the correct answer because it is the study of non-moving bodies under known loads and how forces affect static (non-moving) bodies. This branch of physics focuses on analyzing the equilibrium of forces acting on objects at rest. It is concerned with the balance of forces and moments on objects, without considering their motion or acceleration.
