Q3. The reaction of the ballast on the railway tie can be assumed uniformly distributed over its length as shown below. The tie has the rectangular cross section with thickness, t = 170 mm. 75 kN 0.45 m -1.5 m- W 75 kN 0.45 m 300 mm Determine the maximum bending stress developed in the tie. Express the answer to three significant figures and the appropriate units.

The pressure tank shown has an outside diameter of 100 mm and a wall thickness of 10 mm. Determine the absolute maximum shear stress at point H on the inner surface if the internal gauge pressure is 1.25 MPa and the applied torque is 375N•m. Show the stress state in matrix form and calculate eigenvalues.

Problem 2 The series of bars shown have their diameters from left to right decreasing by 3 mm, and lengths increasing correspondingly by 0.3 m. If the leftmost member has a diameter and length of 28 mm, 1.8 m, respectively, determine the nodal displacements, member forces and the value of P if the node where P acts undergoes a rightward displacement of 4.5 mm. E=180 GPa for all members. Use your calculator. 90 N/mm 45 N/mm 60 N/mm 30 KN -50 KN

A simple pin-connected truss is loaded and supported as shown. The truss is constructed from three aluminum members, each having a cross-sectional area of A = 1480 mm2. Assume a = 1.3 m, b = 6.0 m, and c= 3.6 m. If P = 55 kN and Q = 75 kN, determine the normal stress in each member. P 0← L. Answers: OAB = i OBC= i JAC = i a B MPa (C) MPa (T) MPa (T)

The simply supported joist is used in the construction of a floor for a building. In order to keep the floor low with respect to the sill beams C and D, the ends of the joist are notched as shown. If the allowable shear stress is tallow = 350 psi and the allowable bending stress is s allow = 1700 psi, determine the smallest height h so that the beam will support a load of P = 600 lb. Also, will the entire joist safely support the load? Neglect the stress concentration at the notch.

In a 2.5 cantilevered I-beam, 2500 kg weight is applied at 0.75 meter from the free end. If the allowable stress in beam is 120 Mpa, determine the section modulus and The base and height of the beam if the base is 75% of its height mm.
