A $30ft$ long timber beam $)=(2,100$ksi is subjected to four concentrated loads as shown below. Calculate and draw the shear force, bending moment and curvature diagrans. Show all the important values. Find the maximum flexural stresses and shear stresses in the beam and indicate where they occur $($both along the length of the beam and where in the height of the section$).$ Ignore the self$-$weight of the beam. As a bonus practice problem $($not required to complete this$),$ calculate the deflection at midspan using any method you are familiar with.
