The uniform slender bar shown in Figure 1 is pinned at a distance  l= 27.3cm from its center of mass. The bar is released from rest with θ = 19◦ with the force of gravity acting in the -y-direction shown in the figure. The bar is 99cm long and has a mass of 16kg. Determine the reaction at A immediately after release.

A student suspends a chain consisting of three links, each of mass  m = 0.210 kg, from a light rope as shown in (Figure 1). The rope is attached to the top link of the chain, which does not swing. She pulls upward on the rope, so that the rope applies an upward force of 9.50 N  to the chain. (I) Draw a free-body diagram for the entire chain, considered as an object, and one for each of the three links. (II) Use the diagrams of part (I) and Newton's laws to find (i) the acceleration of the chain, (a) the force exerted by the top link on the middle link, and (b) the force exerted by the middle link on the bottom link. Treat the rope as massless. (III)There are four objects of interest in this problem: the chain as a whole and the three individual links. For each of these four objects, identify the external forces acting on them. Besides the force of gravity, you should include only forces exerted by other objects that touch the object in question. Throughout this problem, assume the…

solve fast i need clear ans and solve  very very fast in 20 min and thank you |

Please could I have the solutions for this question in a step-by-step form. Thank you very much.

Find the weight of WB necessary to hold WC in the position shown, given:WC = 250 N, θ = 20 °, Φ = 10 °, x,y,h = 4,3,5, respectively

18 B 77 L-2 -L- A -x- Persons A and B are standing on a board of uniform linear density that is balanced on two supports, as shown in the figure. What is the maximum distance x from the right end of the board at which person A can stand without tipping the board? Treat persons A and B as point masses. The mass of person B is 1.75 times that of person A, and the mass of the board is 0.359 times that of person A. Give your answer in terms of L, the length of the board.
