Part A - Maximum allowable pressure in the cylindrical pressure vessel Learning Goal: To calculate the maximum allowable stresses in pressure vessels, compute the minimum allowable thickness of pressure vessels to meet certain constraints, and observe and compare properties of different pressure vessel shapes. Engineers are considering two possible vessel shapes for storing fuel. One shape is cylindrical and the other is spherical. Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal...

Learning Goal: To calculate the normal and shear stresses at a point on the cross section of a column. The state of stress at a point is a description of the normal and shear stresses at that point. The normal stresses are generally due to both internal normal force and internal bending moment. The net result can be obtained using the principle of superposition as long as the deflections remain small and the response is elastic. Figure < 1 of...

Learning Goal: To determine the angle of twist for a circular shaft that is composed of varying cross sections and that is subjected to a given power and frequency load. As shown, a shaft is composed of five cylindrical sections. A motor is attached at Fand supplies the shaft with P = 235.0 hp at a speed of w = 1800 rpm. This power is transferred through the shaft without any loss and is completely removed by the pulley at...

The cylindrical pressure vessel has an inner radius of 1.25 m
and a wall thickness of 25 mm . It is made from steel plates that
are welded along the 45∘ seam. The vessel is subjected to an
internal pressure of 7 MPa . (Figure 1)

Learning Goal: To calculate the shear stress at the web/flange joint in a beam and use that stress to calculate the required nail spacing to make a built- up beam. A built up beam can be constructed by fastening flat plates together. When an l-beam is subjected to a shear load, internal shear stress is developed at every cross section, with longitudinal shear stress balancing transverse shear stress. If the beam is built up using plates, the fasteners used must...

Learning Goal: To determine the maximum shear force that can be applied to two shafts of varying cross sections: a solid square shaft and a hollow square shaft. The two square cross sections shown below (Figure 1) are each subjected to a vertical shear force, V. The side length of each cross section is s = 6.00 in and the side length of the hollowed- out portion of the second cross section is r = 2.25 in. The maximum allowable...

Learning Goal: To be able to calculate the velocity and the angle of trajectory of an object undergoing projectile motion. (Figure 1)A batter hits a softball over a third baseman's head with speed Vy and at an angle from the horizontal. Immediately after the ball is hit, the third baseman tums and runs at a constant velocity v = 7.000 m/s, for a time t=2.000 s. He then catches the ball at the same height at which it left the...

Learning Goal: To apply the ideal gas law to problems involving
temperature, pressure, volume, and moles of a gas. The four
properties of gases (pressure P, volume V, temperature T, and moles
of gas n) are related by a single expression known as the ideal gas
law: PV=nRT The variable R is known as the universal gas constant
and has the value R=0.0821 L⋅atm/(mole⋅K). The units of R dictate
the units for all other quantities, so when using this value...

Learning Goal: To calculate torsional deformation and shear stress due to an applied force in a door handle design. A locked door handle is composed of a solid circular shaft AB with a diameter fb = 105 mm and a flat plate BC with a force P = 76 N applied at point C as shown. Let c = 543 mm, d = 125 mm, and e = 145 mm. (Treat the handle as if it were a cantilever beam.)...
