Applied Mechanics and Graphic Statics When a body slides down an inclined surface, the acceleration (f) of the body, is given by f = g cos θ f = g f = g sin θ f = g tan θ f = g cos θ f = g f = g sin θ f = g tan θ ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If a body is lying on a plane whose inclination with the horizontal is less than the angle of friction, then i. a force is required to move the body upwards ii. a force is required to move the body downward iii. the body will not be in equilibrium The correct answer is only (i) both (i) and (iii) both (i) and (ii) only (ii) only (i) both (i) and (iii) both (i) and (ii) only (ii) ANSWER DOWNLOAD EXAMIANS APP
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 3 1/4 4 1/3 3 1/4 4 1/3 ANSWER DOWNLOAD EXAMIANS APP
