A man holds a 35-kg ladder in his hands perpendicular to his hands (Figure 6). The free body diagram is shown on the right. If the maximum compressive force the person can withstand is 400N, determine: a) The minimum value of θ so that the person is able to hold the ladder. b) The compressive force at the end of the ladder at that time

2. For the frame and loading shown to below, determine the components of the reactions at B and D if the force P = 100 lb. a) Draw the free body diagram of the entire frame and free body diagrams for all the components of the frame. Identify any two-force members and use this information in your calculations. Draw and label all forces. b) Find the x- and y- components of the reactions at B and D. Ans: Bx = 64 lb →, By = 48 lb ↑, D, = 64 lb , D, = 52 lb ↑ (By the way, FBC = 80 lb (T)) %3D %3D %3D 2 in. y А В 3 in. C 4 in. 5 in. 10 in.

Question 2) Determine all member (internal) forces on the system given that P is 35 N, and c is 1000 cm. 2P Oc = 80° !! Og = 40° = 60° D B c/2- c/2-

Hey...please help me here 1) Calculate the magnitude of the force in member CA in Newtons. 2) calculate the magnitude of the reaction force's horizontal and vertical component at the pin connection B in newtons.

Two weights, A and C, are fixed to a bar, B. Their masses are: A = 60 kg, B = 230 kg,C = 45 kg. B is, in turn, connected to a fixed vertical post by a hinge and a support cableD. The geometry of the system is shown at right. Treat weights A and C as point masses a)What is the tension in support cable D? Be sure to include a detailed freebody diagram to accompany your analysis.b) What is the magnitude of the force provided by the hinge?c) What is the moment of inertia of the A + B + C as a rigid system, for rotationabout the hinge? For analysis, break the beam into a short piece to the left of thehinge, and a separate longer piece to the right of the hinge. If the support cable D on should break,d) what is the angular acceleration of the beam and weights at the moment the cable breaks?e) what is the magnitude of the linear acceleration experienced by each of the weights, A and C, at moment the cable breaks?
