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 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) ω² (l sin ϕ - r cos θ tan ϕ) ω (l sin ϕ + r cos ϕ tan θ) ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics Kinetic friction may be defined as Ratio of limiting friction and normal reaction Friction force acting when the body is just about to move Friction force acting when the body is in motion Angle between normal reaction and resultant of normal reaction and limiting friction Ratio of limiting friction and normal reaction Friction force acting when the body is just about to move Friction force acting when the body is in motion Angle between normal reaction and resultant of normal reaction and limiting friction ANSWER DOWNLOAD EXAMIANS APP
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 e4* e*72 e2* 1 e4* e*72 e2* 1 ANSWER DOWNLOAD EXAMIANS APP
