Advanced dynamics

Determine the angular velocity and angular acceleration of the disk if β is constant at 30º. See attached file for full problem description.

Relative Acceleration Problem, one ar along a straight line and the other along a curved path.

One of the toughest problem in Dynamics. Problem– At the instant shown, car A has a speed of 20 km/h, which is being increased at the rate of 300 km/h2 as the car enters an expressway. At the same instant, car B is decelerating at 250 km/h2 while traveling forward at 100 km/h. Determine the velocity and acceleration of A with respect to B.

A tricky string pulley problem in dynamics.

A tricky string_pulley problem. Problem # 2 – If the end of the cable at A is pulled down with a speed of 2 m/s, determine the speed at Which block B rises. Give logical explanation i.e. qualitative as well as quantitative way. For figure, please see attached file.

Advanced engineering dynamics

See attached file for full problem description. Please use energy approach. T1+W1-2=T2, T1=0, T= ½ ( m x V ²). T= T gear + T bar+ T collar, T collar = T bar=0.
