Engineering Mechanics If a given force (or a given system of forces) acting on a body __________ the position of the body, but keeps it in equilibrium, then its effect is to produce internal stress in the body. Does not change Change Changes periodically None of these Does not change Change Changes periodically None of these ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.) P = m/W + C P = mW + C P = mW - C P = C - mW P = m/W + C P = mW + C P = mW - C P = C - mW ANSWER DOWNLOAD EXAMIANS APP
