2. Find the reaction forces at point A( roller support) and B (hinge support). Assume that the cross-section is I beam W6*9. Find the maximum and minimum in-plane shears and also the maximum and minimum bending stress. 4. A 30 lb/ft 10' 20 lb * 10' B

1. Find the reaction forces and moment value at Point A (fixed support) and draw Shear & Moment Diagrams. Also, calculate the maximum and minimum in-plane shear for a rectangular cross-section width of 4" and height of 6". 10' 5 lb * 10' 20 lb X

Figure Q2 shows the cross section of a beam. The beam is simply supported over a span of 6 m and carries a vertical point load of 40 kN acting at its mid-span. Calculate  The position of the horizontal centroidal axis of the cross-section from its bottom. The second moment area of the cross-section about the horizontal centroidal axis  The maximum shear load per unit length (metre) at the lower surface of the top flange

Find the max shear stress in bending in the cross section below if Vmax = 10 kips. 10" Flange 2" Web 2" 8" Flange 2" 10" • Identify where in the cross section the max shear will occur. Determine the thickness of the cross-section at the location you wish to find shear stress. • Calculate the Ix for the shape (assume bending in the x with most basic beams). • Calculate Q by dividing the section into two pieces at the point you want shear stress. Select one of the pieces (either will work), I picked the top piece. Use the Shear Stress equation to determine the requested stress. Compare you answer: Max shear stress = at the center of the cross section.

The bending moment M is applied to the box beam in the x-y plane at the orientation show below. (a) Determine the maximum magnitude of the bending moment M so that the tensile bending stress in the member does not exceed 15 ksi. (b) Determine the angle that the neutral axis makes with the y-axis. (c) The position or positions on the beam where the maximum compressive bending stress occurs given your answer in a. Clearly indicate this on the figure below (also calculate the values) 4 in. B 4 in. M 6 in. 6 in.
