Engineering Mechanics If u₁ and u₂ are the velocities of two moving bodies in the same direction before impact and v₁ and v₂ are their velocities after impact, then coefficient of restitution is given by (v₁ - v₂)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (u₁ - u₂)/(v₁ - v₂) (v₂ - v₁)/(u₁ - u₂) (v₁ - v₂)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (u₁ - u₂)/(v₁ - v₂) (v₂ - v₁)/(u₁ - u₂) 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 = C - mW P = mW - C P = mW + C P = m/W + C P = C - mW P = mW - C P = mW + C ANSWER DOWNLOAD EXAMIANS APP
