A beam of T-section is pin-joint supported at point A and simply supported at point B with an overhang section BC shown in Figure 2. The cross section has the width b-65 mm, height h 75 mm and thickness / -13 mm. (a) Determine the support reactions at points A and B. (b) With the aid of bending moment of diagram, determine the maximum tensile and compressieve stresses in the beam.

Could you please provide a conceptual explanation with this?

The two vertical steel [E = 200 GPa] rods that support rigid bar ABCD are initially free of stress. Rod (1) has an area of A1 = 410 mm2 and a length of L1 = 3.2 m. Rod (2) has an area of A2 = 355 mm2 and a length of L2 = 1.3 m. Assume dimensions of a = 3.4 m, b = 1.2 m, and c = 1.5 m. After a load of P = 50 kN is applied to the rigid bar at D, determine: (a) the normal stresses in rods (1) and (2) (b) the magnitude of the downward deflection of the rigid bar at D. y,v (2) L2 a B C D x,u Rigid bar |(1) Answer: (a) o1 = i MPa 02 = i MPa (b) VD = i mm

If the maximum bending stress at section a–a is not allowed to exceed an allowable stress of 220 MPa, determine the maximum allowable force P that can be applied to the end E.

A steel [E = 200 GPa] bar (1) supports beam AB. The cross-sectional area of the bar is 540 mm?. If the stress in the bar must not exceed 450 MPa and the maximum deformation in the bar must not exceed 20 mm, determine the maximum load P that may be supported by this structure. Use dimensions of a = 4 m, b = 2.4 m, and c = 5.2 m. (1) B' A a Answer: P = i kN

Either all parts or none.... I vll upvote definitely

Please show your complete solution. Thank you!The three-member space truss supports the loading of F= 1000N. Determine the force reactions at B, C, and D.

Q4: For the figure below, determine the principal stresses and show them on a sketch of a properly oriented element. Also, find the maximum shear stresses and show them on a sketch of a properly oriented element. (Consider only the in-plane stresses.) -30MPA 90 MPa -34MPA

Please show complete solution. Thank you!
