2 . A rectangular beam with a cross section 200 logistik x 90 mm spans 6 metres and posesses uniform weight of 2 kN/m. a) Calculate the reactions. b) Attract the shear force and bending moment diagrams. c) Calculate I actually for the cross section, about the axis of bending. d) Calculate the most compressive anxiety in the light beam, and show exactly where it arises along the duration, and on the cross section. e) Compute the maximum tensile stress in the beam, and have absolutely where that occurs over the length, and the cross section.

a few. The machine aspect shown below can be analysed as an overhung basically supported column. It is manufactured from cast straightener, which is much stronger in compression than in tension. If the optimum stress has to be limited to 31 MPa in tension and 100 MPa in compression, calculate the utmost value with the load L that can be applied.

5. Two 50 millimeter by a hundred and fifty mm solid wood planks happen to be glued collectively to form a To section because shown in the figure listed below. If a bending moment of 5 kNm is placed on the beam acting in regards to horizontal axis (top in compression), a) Find the stresses in the extreme fibers. b) Compute the total compressive force developed by the...
