The robot arm is elevating and extending simulta- neously. At a given instant, 0 = 30°, 6 = 10 deg/s = constant, l = 0.5 m, i = 0.2 m/s, and i = -0.3 m/s². Compute the magnitudes of the velocity v and accel- eration a of the gripped part P. In addition, express v and a in terms of the unit vectors i and j. Ans. v = 0.296 m/s, a = 0.345 m/s² 0.0641+ 0.289j m/s v = a = -0.328i 0.1086j m/s² y T - P

Consider the given pulley system. The rope is drawn towards the motor with a speed of 3 m/s. What is the speed of mass A and in what direction is it moving?

The motor lifts the 40-kg  crate with an acceleration of 6 m/s2 as shown in (Figure 1). Part A: Determine the x and y components of force reaction at the fixed support A using scalar notation. Express your answers in newtons to three significant figures separated by a comma.   Part B:  Determine the couple moment at the fixed support A. Express your answer in kilonewton meters to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.

Please give detailed the solution, Don't just write the equations. (Complete free body diagram must be drawn , Including components)
