Engineering Mechanics According to Newton's first law of motion, To every action, there is always an equal and opposite reaction None of these Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts To every action, there is always an equal and opposite reaction None of these Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts 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 = C - mW P = mW - C P = mW + C P = m/W + C P = C - mW P = mW - C P = mW + C P = m/W + C ANSWER DOWNLOAD EXAMIANS APP
