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 (u₁ - u₂)/(v₁ - v₂) (v₁ - v₂)/(u₁ - u₂) (v₂ - v₁)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (u₁ - u₂)/(v₁ - v₂) (v₁ - v₂)/(u₁ - u₂) (v₂ - v₁)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Maximum, if it acts at the center of gravity of the body Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Different at different points on its line of action Maximum, if it acts at the center of gravity of the body Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Different at different points on its line of action ANSWER DOWNLOAD EXAMIANS APP
