Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Maximum, if it acts at the center of gravity of the body Different at different points on its line of action Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Maximum, if it acts at the center of gravity of the body Different at different points on its line of action 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 = mW - C P = mW + C P = C - mW P = m/W + C P = mW - C P = mW + C P = C - mW P = m/W + C ANSWER DOWNLOAD EXAMIANS APP
