Applied Mechanics and Graphic Statics A weight ‘W’ is suspended at the free end of a light member hinged to a vertical wall. If the angle of inclination of the member with the upper wall is θ°, the force introduced in the member, is W cosec θ W sec θ W sin θ W cos θ W cosec θ W sec θ W sin θ W cos θ ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics Two balls of masses 3 kg and 6 kg are moving with velocities of 4 m/sec and 1 m/sec respectively, towards each other along the line of their centers. After impact the 3 kg ball comes to rest. This can happen only if the coefficient of restitution between the balls is 1/5 3/5 2/3 1/3 1/5 3/5 2/3 1/3 ANSWER DOWNLOAD EXAMIANS APP
