A vertical hollow steel tube is 2.5 m long. Its internal diameter is 5 cm and its external diameter is 6 cm. Calculate the increase in length of the tube when a load of 1.5 x 10 kg is suspended from the lower end. For steel Young's modulus is 21 x 1010 N m2 and the shear modulus is 8.3 x 1010 N m-

Problem 9: The following steel structure is subjected at point A along the y axis, where there is also a spherical (ball) hinge, which constraints translations along x, y, and z at A, and there is a plane hinge at C. This plane hinge is contained in the x-z plane, which means it constraints translations along the x and z-axes. The force of 500 N at F is also contained in the x-z plane, forming 45° with the x-axis. The...

As shown in Figure 8, the structural member (beam) is 7m long, carries a 2 kN point load, a 1.2 kN/m uniformly distributed load and is supported at points A and B. The beam is constructed from two pieces of steel plate (2 at 80mm x 8mm) that are welded together with 3mm welds. Section properties for the beam are also listed. Given the support reactions as RAv 5.8 kN and RBv 2.2 kN, as well as the shear force...
A rectangular cross section at a location along a beam in bending is
(a). A rectangular cross section at a location along a beam in bending is acted upon by a bending moment and a shear force. The cross section is \(120 \mathrm{~mm}\) wide, \(300 \mathrm{~mm}\) deep and is orientated such that it is in bending about its major axis of bending. The magnitudes of the bending moment and shear force are \(315 \mathrm{kNm}\) and \(240 \mathrm{kN}\) respectively. Determine the maximum bending and shear stresses on the cross section. Plot the bending and...

1.) Where is the reference point located when taking the
moment? How did they get the sum of the moments equal to the
solution given? ------I'm confused on how they got Fcos30(.025m/2)
why did they divide the 0.025 by 2? where is the reference
point?
2.) Why did they make the combined stress equal to the
yield stress 276MPa?

Given: F = mg where g = 9,8 N/kg (55 marks] 1. An experiment was done to see how the contact surface area affects the force of friction between a wooden block and a granite table. The contact surface area was changed by placing the block on its different sides. The force required to pull the block along at constant speed was measured with the spring-balance.
