A bar made of A-36 steel has the dimensions shown in the figure below. If an axial force of P = 100 kN is applied to the bar, determine the change in its length after applying the load. The material behaves elastically. Use a modulus of elasticity E = 200 GPa. y Diagram P= 100 kN Description automatically generated 80 mm 2 m P= 100 kN 160 mm

The band in the figure below is stainless steel (coefficient of linear expansion = 17.3 ✕ 10−6°C−1; Young's modulus = 18 ✕ 1010 N/m2). It is essentially circular with an initial mean radius of 5.4 mm, a height of 4.4 mm, and a thickness of 0.51 mm. If the band just fits snugly over the tooth when heated to a temperature of 81°C, what is the tension in the band when it cools to a temperature of 37°C?

6.6 Consider a cylindrical nickel wire 2.0 mm + (0.08 in.) in diameter and 3 × 10ª mm (1200 in.) long. Calculate its elongation when a load of 300 N (67 lb,) is applied. Assume that the defor- mation is totally elastic.

Mechanics of Deformable Bodies Problem: The figure shows the upper half of a built up girder( the cross section is symmetric about the neutral axis). All rivets used in fabrication have a diameter of 22 mm. The moment of inertia of the entire cross sectional area of the girder about the neutral axis is l=4770x10⁶mm⁴. The working stresses are 100 MPa for rivets in shear and 280 MPa for bearing of the web plate. If the maximum shear force carried by the girder is 450 kN, determine the largest allowable spacing of rivets that join the angles to the web plate.

A high-strength bolt that is passing through a steel plate is subjected to a tension force of P=4.6 kN as shown in the figure. The hole in the metal plate has a diameter of D=14 mm which is bit larger than the diameter of the bolt (d, = 12 mm) to allow for easy installation process. The plate has a thickness of t= 11 mm. The bolt head has a thickness of a = 3 mm and an outer diameter of dh = 19 mm. Determine the bearing stress between the bolt head and the steel plate.
