Applied Mechanics and Graphic Statics ‘u₁’ and ‘u₂’ are the velocities of approach of two moving bodies in the same direction and their corresponding velocities of separation are ‘v₁’ and ‘v₂’. As per Newton's law of collision of elastic bodies, the coefficient of restitution (e) is given by e = v₂ - v₁/u₁ - u₂ e = u₂ - u₁/v₁ - v₂ e = v₁ - v₂/u₂ - u₁ e = v₁ - v₂/u₂ + u₁ e = v₂ - v₁/u₁ - u₂ e = u₂ - u₁/v₁ - v₂ e = v₁ - v₂/u₂ - u₁ e = v₁ - v₂/u₂ + u₁ ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics The following is not a law of static friction: The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact The force of friction depends upon the roughness of the surface The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact The force of friction depends upon the roughness of the surface ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to Half the original velocity in the opposite direction Original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction ANSWER DOWNLOAD EXAMIANS APP
