- The 919-kg uniform bar AB is suspended from two cables AC and BD each with cross-sectional area 321 mm2. Find the location x (in mm) of P that can be safely applied to the bar if the stresses in AC and BD are limited to 112 MPa and 57 MPa, respectively. Express your answer in two decimal places.Situation 4. A cast iron link is 50mm wide by 250mm high by 550 mm long. The allowable stressin tension is 50 MPa and 85 MPa in compression. Assume that load P (tensile axialload) is placed at 30 mm distance from the neutral axis. A. What is the value of tensile normal stress in MPa? B. What is the value of bending stress in MPa? C. What is the value of the combined stress?The two-bar structure shown is pinned at A, B, and C. A sign weighing 20 kN is suspended from bar BC at points D and E, which are located at 0.8 m and 0.4 m, respectively, from the ends of the bar BC. If member AB is a steel pipe with inside diameter 20 mm, determine the smallest permissible outer diameter of the member if the working stress in steel is not to exceed 140 MPa.
- The beam is loaded by two point forces P. The beam is assembled according to the cross-sectional view by nailing wooden parts with cross-sections of 50 mm x c = 220 mm and 25 mm x d = 260 mm. How large can the value of the load P be when the distance between the nails in the longitudinal direction of the beam is 100 mm, the cross-sectional area of the nail is 9 mm2 and their permissible shear stress is 110MPa? Then calculate the maximum stresses and shear stresses of the beam at that load when the distance between the articulated supports is L = 1.9 m and the length of the beam projections a = 1.3 m. Permissible shear force of one nail? kN Static torque of the cutting surface? mm^3 Maximum torque change in cantilever? kNm Cutting force of the projection? kN Magnitude of force P? kN Calculated with the obtained force P maximum normal stress?

The two outer wires are steel and the middle wire is brass. Calculate: a) Stresses in the wiresAxial loads are applied to the compound rod that is composed of an aluminum segment rigidly connected between steel and bronze segments.

- The figure shows a single acting rivet connecting steel plates. Rivet diameter d = 22 mm,plate thicknesses are t1 = 20 mm, t2 = 12 mm, plate width b = 100 mm and e = 38 mm. The shear strength in the material is τem = 100 MPa, the safety stress in pressure and tension is σL = 280 MPa andSince σem = 140 MPa, determine the maximum force P that the joint can safely carry.A steel rod of 15- mm diameter is held snugly (but without any initial stresses) between rigid walls by the arrangement shown in the figure part (a). (For the steel rod, use α = 12 x 10-6/˚C and E = 200 GPa.) Calculate the temperature drop ΔT (degrees Celsius) at which the average shear stress in the 12 – mm diameter bolt becomes 45 MPa. Also, what is the normal stress in the rod? What are the average bearing stresses in the bolt and clevis at A and between the washer (dW = 20mm) and wall (t = 18 mm) at B? If the connection to the wall at B is changed to an end plate with two bolts (see figure part b), what is the required diameter db of each bolt if the temperature drop is ΔT = 38˚C and the allowable bolt stress is 90 MPa?4. The joint is fastened together using two bolts. The diameter of each bolt is 13.5 mm. Determinethe average shear stress experienced by each bolt.
