You are playing basketball with some friends at the park when Nate Robinson, the 180 Ib(f) former New York Knicks point guard and only three-time winner of the NBA Slam Dunk Contest, stops by. You are curious about the forces the members of the hoop apparatus experience during a dunk. If Nate dunks and hangs on the rim of the hoop, find the forces supported by each member of the apparatus and the support reactions at D. Member IJ is a hand crank which can be used to adjust the height of the rim, and it acts as a two-force member. Post ABCD weighs 400 N and has a center of mass at noint C The assembly FEGH weighs

4. Assuming you know the geometry of the ropes, you cannot determine the forces in the cables in which system below? (A) 1000 lb (B) 1000 lb 24 (C) 1000 lb

Boom OAB is supported by a ball and socket at point O and two cables AC and AD. Determine the forces supported by the two cables and the support reactions at O if P = 520 KN.

Write down equations for static equilibrium. Calculate the moment about C, and leave the answer in terms of the unknow force of magnitude |FB| After that Caclulate |FB|

QB2: Determine the force in members GH, GB, and BC, and state whether each of these three members is in tension (T) or compression (C), or whether it is a zero-force member (ZFM). Solve this problem using the Method of Sections. [Туре C for LO 3.2, 3.4] 3 kN 3 kN 3 kN 1 kN 1 kN 45° 4m 1m 3 m 3 m 3 m 3 m

(2) An artist designs an oval mobile that is supposed to hang horizontal as shown. If the weights at both A and B are each 8 kN, what is the tension at C and the counterweight force at D? You may neglect the weight of the oval. 2 m 1 m 2 m

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The hydraulic cylinder BD exerts on member ABC a force P directed along line BD. The force P must have a 770-N component perpendicular to member ABC. B P 50% 60° Determine the magnitude of the force P. (You must provide an answer before moving on to the next part.) The magnitude of the force P is N.

The boxes are at rest. The pulley is massless. Fpull makes an angle 0 with respect to the incline. (i) Draw free body diagrams for m, and m, for the situation outlined in part (ii). (ii) What maximum force, Foull, Can you apply to m, and have it remain at rest? In terms of the given information. Just give the equation (or equations) needed to solve for the force. Do not simplify or isolate for Fpull, but make sure it is the only unknown. pull Given information: B (angle of incline with horizontal) e (angle Fpull makes with incline) m, (mass of box 1) m2 (mass of box 2) H (distance m, is above the ground) • H, (static friction coefficient, incline and box 1) He (kinetic friction coefficient, incline and box 1) m1 m2
