_‘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$? |
| A. | ω² (l cos ϕ + r sin ϕ tan θ) |
| B. | ω² (l sin ϕ + r cos φ tan θ) |
| C. | ω (l sin ϕ + r cos ϕ tan θ) |
| D. | ω² (l sin ϕ - r cos θ tan ϕ) |
| Answer» D. ≈ì√¢¬¨‚⧠(l sin ≈ì√Ø - r cos ≈í‚àè tan ≈ì√Ø) | |
