Applied Mechanics and Graphic Statics A rope is wrapped twice around a rough pole with a coefficient of friction ‘A . It is subjected to a force Fj at one end and a gradually increasing force F2 is applied at the other end till the rope just starts slip-ping. At this instant the ratio of F2 to Fi is 1 e*72 e2* e4* 1 e*72 e2* e4* ANSWER DOWNLOAD EXAMIANS APP
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 ω² (l sin ϕ - r cos θ tan ϕ) ω (l sin ϕ + r cos ϕ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ + r cos φ tan θ) ω² (l sin ϕ - r cos θ tan ϕ) ω (l sin ϕ + r cos ϕ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ + r cos φ tan θ) ANSWER DOWNLOAD EXAMIANS APP
