The 30-kg uniform thin hollow square plate is pinned at point 0, and its side L = 0.2 m. If it is subjected to the constant moment M = 62 N•m and is released from rest from the position as shown, determine the total work done to it when it has rotated 45. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s².

4. For this series of 4 questions, two blocks, A and B, are connected using the cable and pulley system as shown. (The cable and pulley system is friction-less and weight- less.) The coefficient of kinetic friction between block A and the inclined plane is μk = 0. 2. Initially the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 3) If the blocks and the cable-pulley system are considered as one system, during this process from the blocks moving to them coming to stop, which forces are doing work to this system? A B C D Weight of block B. Weight of block A. Friction between block A and the incline plane. Tension force in the cable connecting to block B. Tension force in the cable connecting to block A.

The slider P can be moved inward by means of the string S as the bar OA rotates about the pivot 0. The angular position of the bar is given by 0 = 0.4 +0.12t+ 0.06t³, where 0 is in radians and t is in seconds. The position of the slider is given by r = 0.8 0.1t 0.05t2, where r is in meters and t is in seconds. Determine and sketch the velocity and acceleration of the slider at time t = 2 s. Find the angles a and ß which v and a make with the posi- tive x-axis. S 0 Problem 2/144 رفع جك

Need only a handwritten solution only (not a typed one).

The reaction forces applied by the unbalanced loads on the shaft to the A and B bearings,FA = 3i N and FB = 4i N. If the shaft rotates at 300 rpm, specify the magnitude of the unbalanced loads (in kg.mm) and find their angular positions. Distances are given with a= 200 mm and b = 300 mm. (Note that the angles θ1 and θ2 are not known.)

The thin rod of the figure has a mass of 15kg and is attached to a spring of constant K = 50 N/m at one end, which has an unstretched length of 1.5 m. If the rod is released from rest in horizontal position (ø = 0°) and only conservative forces act on it, determine: a) What is the moment of inertia of the thin rod around the axis of rotation in A? b) What is the angle at which the rod is momentarily resting again? c) What is the maximum angular speed of the route? Please attach the free body diagram if necessary. Thank you!
