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 43835 43864 43895 43833 43835 43864 43895 43833 ANSWER DOWNLOAD EXAMIANS APP
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 sec θ W cos θ W cosec θ W sin θ W sec θ W cos θ W cosec θ W sin θ ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If two forces each equal to ‘T’ in magnitude act at right angles, their effect may be neutralized by a third force acting along their bisector in opposite direction whose magnitude will be 3 T √2 T 2 T 1/2 T 3 T √2 T 2 T 1/2 T ANSWER DOWNLOAD EXAMIANS APP
