Applied Mechanics and Graphic Statics A ladder of weight 'w' rests against a smooth vertical wall, and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being 1/4. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan'1 x, where x is 4 1/3 3 1/4 4 1/3 3 1/4 ANSWER DOWNLOAD EXAMIANS APP

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 30 m/sec 50 m/sec 40 m/sec 20 m/sec 30 m/sec 50 m/sec 40 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics One end of an elastic string of natural length ‘l’ and modulus ‘X’ is kept fixed while to the other end is attached a particle of mass m which is hanging freely under gravity. The particle is pulled down vertically through a distance ‘x’, held at rest and then released.The motion is A damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed None of these A damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed None of these ANSWER DOWNLOAD EXAMIANS APP
