Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 20 m/sec 40 m/sec 50 m/sec 30 m/sec 20 m/sec 40 m/sec 50 m/sec 30 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The ends of a string weighing w/metre are attached to two points at the same horizontal level. If the central dip is very small, the horizontal tension of the string throughout is wl²/8d wl/4d wl²/4d wl²/16d wl²/8d wl/4d wl²/4d wl²/16d ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics When a body slides down an inclined surface, the acceleration (f) of the body, is given by f = g sin θ f = g f = g cos θ f = g tan θ f = g sin θ f = g f = g cos θ f = g tan θ 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: 60 g 40 g 80 g 100 g 60 g 40 g 80 g 100 g ANSWER DOWNLOAD EXAMIANS APP
