Applied Mechanics and Graphic Statics A rod 5 m in length is moving in a vertical plane. When it is inclined at 60° to horizontal, its lower end is moving horizontally at 3 m/sec and upper end is moving in vertical direction. The velocity of its upper end, is 0.5 m/sec 1.0 m/sec 2.5 m/sec 1.5 m/sec 0.5 m/sec 1.0 m/sec 2.5 m/sec 1.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A body A of mass 6.6 kg which is lying on a horizontal platform 4.5 m from its edge is connected to the end of a light string whose other end is supporting a body of mass 3.2 kg as shown in below figure. If the friction between the platform and the body A is 1/3, the acceleration is 1.25 m/sec² 0.5 m/sec² 0.75 m/sec² 1.00 m/sec² 1.25 m/sec² 0.5 m/sec² 0.75 m/sec² 1.00 m/sec² ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A string of length 90 cm is fastened to two points ‘A’ and ‘B’ at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force ‘P’ is applied to the ring such that it is in equilibrium vertically below ‘B’. The value of ‘P’ is: 80 g 40 g 60 g 100 g 80 g 40 g 60 g 100 g ANSWER DOWNLOAD EXAMIANS APP
