3. The beam is made of steel that has an allowable shear stress of tall. a) Find the reactions at all the supports; b) Draw the shear diagram. c) Where does the maximum shear occur (Considering the distance from the left side) and based on that maximum shear, determine the dimensions of its cross section (b and d) if it is a rectangular having a height-to width ratio of r. Use FS as the safety factor P 4m +1m- 6 m
