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 same direction Half the original velocity in the opposite direction Original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the opposite direction Half the original velocity in the same direction ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If two bodies of masses M1 and M2(M1 > M2) are connected by alight inextensible string passing over a smooth pulley, the tension in the string, will be given by T = g(M2 + M1)/(M2 - M1) T = g(M2 - M1)/(M1 + M2) T = g(M1 - M2)/(M1 + M2) T = g(M1 + M2)/(M1 × M2) T = g(M2 + M1)/(M2 - M1) T = g(M2 - M1)/(M1 + M2) T = g(M1 - M2)/(M1 + M2) T = g(M1 + M2)/(M1 × M2) 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 √2 T 2 T 3 T 1/2 T √2 T 2 T 3 T 1/2 T ANSWER DOWNLOAD EXAMIANS APP
