Problem 3 • Determine the resultant moment about point A of the system. Each square is 1 ft on a side. 100 lb A 80 lb 80 lb 100 lb mathalino.com 100 lb 200 lb

For the design of the band brake shown, find the couple M required to turn the pipe in the V-block against the action of the flexible band. A force P = 31 lb is applied to the lever, which is pivoted about O. The coefficient of friction between the band and the pipe is 0.26, and that between the pipe and the block is 0.35. the weights of the parts are negligible. B M * 10" 45% 00 35° 35° 5 A Answer: M = | the tolerance the tolerance is +/-5% lb-in. 16" P

Gate AB in the image is a quarter circle 10 ft wide along the z axis and hinged at B. Find the force F just sufficient to keep the gate from opening. The gate is uniform and weighs 4350 lbf. Round the final answer to two decimal places. lbf A r=8 ft Water

A bolt needs to be tightened to a degree that is equal to a moment amounting to 60 N-mm. If a 14-inch cross wrench will be used, how much force should be applied on both ends of the wrench to tighten the bolt? If ϴ = 60 deg, find the following:a)x and y components of 900 lbb)x and y components of 500 lb

Using the Laws of Static Equilibrium determine Reaction Left and Reaction Right. EACH block on grid =1ft  Eg. 20 blocks = 20ft

Please write the solution on paper.

A carpenter holds a 17-lb 2-in. by 4-in. board as shown. If he exerts vertical forces on the board, determine the forces at A and B (use positive if the force is up and negative if down). Answers: NA = NB = i i B 9¹ lb lb
