Concept explainers

Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Question

1. The assembly has the diameters and material indicated, and has the four axial loads applied
(two at location B and two at location C), with P = 12 kips (12,000 lbs). The assembly fits
securely between the supports at A and D when the temperature is T₁ = 70°F. ("Fits securely"
means at 70°F, zero load is applied by the support at D-that is, at 70°F you can assume the
wall is not there). The temperature is raised to T₂ = 110°F (AT= 40°F); with the increase in
temperature, the wall at D becomes a roller support-it prevents movement horizontally but
not vertically.

Problem 1: Three vertical posts AD, BE, and CF are held between two horizontal rigid plates. Posts AD and CF are made of steel (Es = 200 GPa) and have cross sectional areas of 1000 mm² each. Post BE is made of aluminum (Ea = 73.1 GPa) and has a cross sectional area of 1500 mm². Initially, there is a small gap of 0.1 mm between BE and the top horizontal plate. Then a vertical force of P = 410 kN is applied, which is more than sufficient to close the gap completely.
