The forces, which meet at one point and their lines of action also lie on the same plane, are

known as:

(५) Coplanar concurrent forces

(B) Coplanar non-concurrent forces

(C) Non- coplanar concurrent forces

(D) Non- coplaner non-concurrent forces

A couple produces :
(A) Translatory motion
(B) Rotational motion
(0 Combined translatory and rotational motion
(D) None of the above

Elasticity of a body is :
ക) The property by which a body returns to its original shape after removal of the
load
(B) The ratio of stress to strain
)© The resistance to the force acting
(D) Large deformability as in case of rubber

The stress in a member subjected to a force is :
(A) Continued deformation under sustained loading
(B) Load per unit area _
(C) The resistance offered by the material per unit area to a force
(D) The strain per unit length

The volumetric strain is the ratio of the :
(^) Original thickness to the change in thickness
(B) Change in volume to the original volume
(C) Change in thickness to the original thickness
(D) Original volume to the change in volume

The law “Stress is proportional to strain within certain limits” is formulated by :
(A) Thomas Young (B) Poisson
(C) Mohr (D) Robert Hook

Young’s Modulus is the ratio വ്‌ the normal stress to the :
(A) Normal strain within elastic limit
(B) Reciprocal of normal strain within elastic limit
(0) Normal strain within proportional limit
(D) Normal strain at yield point
