A boy stands out at the end of the diving board, which is supported by two springs A and B, each having a stiffness of k = 130lbf/in. In the position shown the board is horizontal. If the boy has a weight of 80 lbf, determine the angle of tilt which the board makes the horizontal after he jumps off. Neglect the weight of the board and assume it is rigid.

You are working in an ice skating rink and have been asked to hang a new banner on the wall. Your friend is helping you so that the ladder does not collapse by exerting a force F_AL at an angle ϕ relative to the horizontal. The ladder has a length L and makes an angle of θ with respect to the vertical wall. You have a mass, m_Y, and are a horizontal distance x from the wall. The ladder has a mass of m_L. Because the wall is slick, and the ice on the floor is slick, the frictional forces acting on the ladder are negligible. Find a formula for the magnitude of the force that your friend must exert to keep the ladder from falling, in terms of the following variables: x,L,m_Y,m_L,θ,ϕ. Then use the following values to get a number for the magnitude of F_AL. θ = 30.3 degrees ϕ = 23.028 degrees x = 1.491 meters L = 7.1 meters m_Y = 86.0 kg m_L = 42.14 kg Find the magnitudes of: F_AL, normal force of the wall on the ladder (N_WL), and normal force of the floor on the ladder (N_FL).
An object is said to be in static equilibrium if the sum of the forces acting on an object is zero. The weight described below is in static equilibrium. A 63-lb weight is suspended by three cables that are anchored at points P (-5, 1,0), Q (-2, -4,0), and R(21/5, 9/5, 0). The weight is located at S(0,0, –63/11);. Let F1, F2, and F3 be the forces of tension resulting from the load in cables SP, SQ, and SR, respectively. Note that because the weight counterbalances the the load in the three cables F1 + F2 + F3 + (0, 0, –63) = (0,0,0), where F1 = a SP, F2 = b and F3 = c SR for some unknown scalars a, b, and c. First solve for the unknowns a, b, and c and use them to find the force vectors F1, F2, and R а, Feel free to use a computational solver like WolframAlpha.com to solve these equations.
