Applied Mechanics and Graphic Statics ‘ω’ rad/sec is the angular velocity of a crank whose radius is ‘r’. If it makes θ° with inner dead centre and obliquity of the connecting rod ‘l’ is ‘ϕ’, the velocity v of the piston, is given by the equation ω (l sin ϕ + r cos ϕ tan θ) ω² (l sin ϕ + r cos φ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ - r cos θ tan ϕ) ω (l sin ϕ + r cos ϕ tan θ) ω² (l sin ϕ + r cos φ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ - r cos θ tan ϕ) ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics The potential energy of a particle falling through a straight shaft drilled through the earth (assumed homogenous and spherical) is proportional to (where r is the distance of’the particle from centre of the earth) r2 r 1/r log r r2 r 1/r log r 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 4 1/4 3 1/3 4 1/4 3 1/3 ANSWER DOWNLOAD EXAMIANS APP
