Question

14. The relative change is the dimensions or

shape of a body, when it is subjected to

external deforming forces is called​

Answer 1

Explanation:

Answer: Mean Deviation = Σ|x − μ|/N. calculate mean of 18,12,15 =(18 +12+ 15) / 3= 15. M.D = Σ(|18-15|+ |12-15| + ...

Answer 2

Answer:

Deformation is the relative alteration in a body's size or shape that results from the application of external deforming forces.

Explanation:

Characteristics of deformation:

• The extent of deformation is always directly proportional to the deforming force.
• The length of a wire (chord), the volume of a body, or the shape of a body changes as a result of a deforming force.
• The body is referred to as being stretched or in a deformed state when deformation occurs.
• In the deformed state, the applied force is numerically equal to the internal elastic restoring force within a body but in the opposite direction.
• Deformation produced in a body is due to changes in relative positions of the molecules within a body, due to applied deforming force.

So, deformation is the relative alteration in a body's size or shape that results from the application of external deforming forces.
