Theory of Machine Flexible coupling is used because It is easy to engage and disengage It is easy to disassemble It transmits shocks gradually It prevents shock transmission and eliminates stress reversals It is easy to engage and disengage It is easy to disassemble It transmits shocks gradually It prevents shock transmission and eliminates stress reversals ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The equation of motion for a vibrating system with viscous damping is (d²x/dt²) + (c/m). (dx/dt) + (s/m). x = 0. If the roots of this equation are real, then the system will be Under damped Critically damped Over-damped Without vibrations Under damped Critically damped Over-damped Without vibrations ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a screw jack, the effort required to lift the load W is given by (where α = Helix angle, and φ = Angle of friction) P = W tan(α + φ) P = W tan(α - φ) P = W cos(α + φ) P = W tan(φ - α) P = W tan(α + φ) P = W tan(α - φ) P = W cos(α + φ) P = W tan(φ - α) ANSWER DOWNLOAD EXAMIANS APP
