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 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) ω (l sin ϕ + r cos ϕ tan θ) ANSWER DOWNLOAD EXAMIANS APP
