1.Determine the maximum bending stress that will occur in a timber beam of rectangular section 250mm x 80mm when a bending movement of 500N is applied about the x-x axis
2.A small blimp is temporarily moored as shown in the diagram wherein DC and the centerline of AB are coplanar. A force F from wind, weight, and buoyancy is shown acting at the centerline of the blimp. If F = 5i+ 10 j + 18 k kN What are the moment vectors from F about A, B, and C ?
