Applied Mechanics and Graphic Statics The forces which meet at one point and have their lines of action in different planes are called Non-coplanar concurrent forces Coplanar non-concurrent forces Non-coplanar non-current forces Intersecting forces Non-coplanar concurrent forces Coplanar non-concurrent forces Non-coplanar non-current forces Intersecting forces 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 Original velocity in the opposite direction Half the original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction Original velocity in the opposite direction Half the original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction 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
