Engineering Mechanics Which of the following statement is incorrect? The ratio of the limiting friction to the normal reaction is called coefficient of friction A force acting in the opposite direction to the motion of the body is called force of friction The velocity ratio of a machine is the ratio of load lifted to the effort applied A machine whose efficiency is 100% is known as an ideal machine The ratio of the limiting friction to the normal reaction is called coefficient of friction A force acting in the opposite direction to the motion of the body is called force of friction The velocity ratio of a machine is the ratio of load lifted to the effort applied A machine whose efficiency is 100% is known as an ideal machine 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
