A prismatic shaft consists of a solid brass rod of diameter 32 mm, which is inside a steel tube of diameter 50 mm. 2GB) Both shafts are firmly (Gs jointed. The combined assembly is subjected to a torque of 1000 Nm. calculate maximum shear stress = developed in steel in N/mm2 (up to 2 decimals)

The brass wire has a triangular cross section, 2mm on a side. The yield stress for brass is Ty= 208 MPa. Gbr= 37 GPa. Determine the maximum torque to which it can be subjected so that the wire will not yield and the angle of twist

The steel bar AB has a diameter of 30mm and is connected to the brass bar BC. The two bars are fixed to unyielding supports at the top (point A) and bottom (point C) ends. If there is a temperature rise of 50°C, calculate the compressive force induced in the rods (ABC). Note: For steel (E = 200 GPa, as = 11.7 x 106 °C) and for brass (E = 105 GPa, qb= 20.9 x 10-6/ °C). 250 mm 300 mm A B -30-mm diameter -50-mm diameter

A rigid bar ABCD is supported by two bars as shown in the figure. There is no strain in the vertical bars before load P is applied. After load P is applied, the normal strain in rod (1) is -1350 µm/m. Determine the normal strain in rod (2) if there is a 1-mm gap in the connection at pin C before the load is applied.
