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 1/3 4 1/4 3 1/3 4 1/4 3 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Maximum efficiency of a screw jack for the angle of friction θ, is (1 - sin θ)/sin θ (1 - sin θ)/(1 + sin θ) (1 + sin θ)/(1 - sin θ) sin θ/(1 + sin θ) (1 - sin θ)/sin θ (1 - sin θ)/(1 + sin θ) (1 + sin θ)/(1 - sin θ) sin θ/(1 + sin θ) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is 3/5 4/5 5/3 3/4 3/5 4/5 5/3 3/4 ANSWER DOWNLOAD EXAMIANS APP
