For the beams and loading shown, using the graphical method: (a) draw the shear and bending moment diagrams. (b) determine the maximum absolute values of the shear and bending moment

Question Three The three-bar truss ABC shown in the figure part a has a span L = 3 m and is constructed of steel pipes having cross-sectional area A = 3900 mm² and modulus of elasticity E = 200 GPa. Identical loads P act both vertically and horizontally at joint C, as shown. (a) If P=475 kN, what is the horizontal displacement of joint B? (b) What is the maximum permissible load value Pmax if the displacement of joint B is limited to 1.5 mm? P A 45° 45° B L (a)

| For the beam illustrated in the figure, with a T-shape cross-section shown on the right, (a) complete the shear (a = ?) and bending moment diagrams and label properly at the point of interest E on the cross section, determine the magnitudes of (b) tensile and compressive bending stresses and (b) maximum transverse shear stress due to V (i. e.at point E, (02)tensile =?, (0z)compressive =?, (Ty)max =?). I is 8.5 in“. 300 Ibf in 3 in 1800 lbf ỹ = 1.5 in I in N. A. A 10 in 8 30 in |R,= 6900 Ibf |R2 = 3900 lbf 2.5 in 3 in V (Ibf | 5100 I in -1800 -3900 M (lbf.in)| x (in)

Solve the problem and answer the questions that follow. - If the supports were swapped such that the left support were a roller and the right support a pin, how would your solution change? - If the value of “w” were doubled, what would be the bending moment at the left most point of the beam?
