Required information Problem 12.092 - Two collars connected on a frame NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Two 2.6-lb collars A and B can slide without friction on a frame, consisting of the horizontal rod OE and the vertical rod CD, which is free to rotate about CD. The two collars are connected by a cord running over a pulley that is attached to the frame at O and a stop prevents collar B from moving. The frame is rotating at the rate 0 = 13.8 rad/s and r D0.6 ft when the stop is removed, allowing collar A to move out along rod OE. Neglect the friction and the mass of the frame. Problem 12.092.a - Transverse component of the velocity of collar A Determine, for the position r= 1.2 ft, the transverse component of the velocity of collar A The transverse component of the velocity is ft/s. Determine, for the position r 1.2 ft, the tension in the cord and the acceleration of collar A relative to the rod OE The tension…

(1) A 50 lb roller, with diameter 10 in, is used to level a tile floor, and is resting directly on the subflooring as shown. If the thickness of the tile is 30° 0.25 in, what is the minimum force P required to pull the roller onto the tiles when it is pulled slowly to the right? Fig. P4.75 and P4.76

6.97 The cab and motor units of the front-end loader shown are connected by a vertical pin located 2 m behind the cab wheels. The distance from C to D is 1 m. The center of gravity of the 300-kN motor unit is located at Gm, while the centers of gravity of the 100-kN cab and 75-kN load are located, respectively, at Go and G₁. Knowing that the machine is at rest with its brakes released, determine (a) the reactions at each of the four wheels, (b) the forces exerted on the motor unit at C and D. 100 KN 0.8 m G₁ 75 kN Fig. P6.97 3.2 m- A 1.2 m Gc -2 m $ D 2.8 m B 300 KN G m

The center of gravity of the 600 kg triangular plate is at the centroid, which is 250 mm to the right of C.  The plate is supported by members DE and BC through pinned connections at E and C.  Member DE is free to slide in block F, which is pinned to member BC.  Determine the pin reactions at C,  which are CX and CY.  At least three FBDs are needed.
