Strength of Materials The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is as per the principle of independence of forces forces resolution of forces. balance of force independence of forces forces resolution of forces. balance of force ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials According to principle of transmissibility of forces, the effect of a force upon a body is The same at every point in its line of action Different at different points in its line of action Minimum when it acts at the C.G. of the body Maximum when it acts at the center of gravity of a body The same at every point in its line of action Different at different points in its line of action Minimum when it acts at the C.G. of the body Maximum when it acts at the center of gravity of a body ANSWER DOWNLOAD EXAMIANS APP

Strength of Materials Pick up wrong statement about friction force for dry surfaces. Friction force is proportional to velocity of sliding dependent on the materials of contact surface proportional to normal load between the surfaces independent of the area of contact surfaces proportional to velocity of sliding dependent on the materials of contact surface proportional to normal load between the surfaces independent of the area of contact surfaces ANSWER DOWNLOAD EXAMIANS APP
