11-35* A body (W = 120 lb) is supported by a flexible ca-ble and a spring (k= 80 lb/in.) as shown in Fig. P11-35. Thepulley over which the cable passes is weightless and fric-tionless. If a force P of 100 lb is slowly applied to the body,what is the change in potential energy ofThe spring?wwwAPFig. P11-35

A FEM analysis was used to analyse the safety of a mechanical component made by an average steel (E = 2 × 105 MPa, v = 0.25, o, = 600 MPa). For a given loading scenario, the stress tensor E in a critical point is: Try -81 -186 Try Oyy 186 -37 -319 Calculate the von Mises equivalent stress oyM and indicate whether or not the stress condition is safe with respect to the related failure criterion. OVM = MPa Is the stress condition safe with respect to the related failure criterion: Oa. Yes Ob. No
A force of Fi = (180 i -250j + 190k) lb is applied to the pipe assembly at point B. A force of F2 -250j + 250k) lb is applied to the pipe assembly at point D.

A uniform board has a length L = 4.0 m and rests horizontally and somewhat above the ground on two cylinders of wood, each supporting the board at a distance of D= 0.75 m from the corresponding end of the board. (The axis of each cylinder is perpendicular to the length of the board.) The board has a mass of ma = 40 kg. A person with a mass of me = 50 kg is about to step on one end of the board. Our goal is to identify if it is safe for the person to step on the board. A. On the diagram below, draw all the forces acting on the board. Assume the person has just stepped on the left end. B. Each of the two wodden cylinders exerts an upward force on the board. Which one of those two forces is larger? If this detail is not evident from your force diagram, redraw it. C. If the board does end up starting to tilt after the person steps on it, what does that imply about the normal force that the right support exerts? D. Is it safe for the person to step on the board?
