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 = m/W + C P = C - mW P = mW - C P = mW + C P = m/W + C P = C - mW ANSWER DOWNLOAD EXAMIANS APP

Engineering Mechanics When two elastic bodies collide with each other, The two bodies will momentarily come to rest after collision The two bodies begin to regain their original shape All of these The two bodies tend to compress and deform at the surface of contact The two bodies will momentarily come to rest after collision The two bodies begin to regain their original shape All of these The two bodies tend to compress and deform at the surface of contact ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called Newton's second law of motion Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum Newton's second law of motion Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum ANSWER DOWNLOAD EXAMIANS APP
