Length and Length related Variables

Length can de defined as the measurement or extent of physical quantities or objects from one terminal to another terminal. Stone age humans used finger length, step length, and so on to measure the size or displacement of an object. Nowadays, depending on how precise the measurement requires to be and the object’s size is measured, we use measuring devices for measurements like rulers and steel tape. Most people have used a ruler or tape measure to measure a particular distance or the size of an object. For more precise measurements of tiny objects, the development of measurement tools such as the Vernier caliper, which permits us to measure dimensions within 1/1000 of an inch. In the last few decades, electronic distance measuring instruments (EDMI) have been implemented that permit us to measure distances from a few feet to many miles with reasonable accuracy.

The figure shows a cutaway view of an assembly in which a solid bronze [G= 6,500 ksi] rod (1) is fitted inside of an aluminum alloy [G = 4,000 ksi] tube (2). The tube is attached to a fixed plate at C, and both the rod and the tube are welded to a rigid end plate at A. The rod diameter is d₁ = 1.55 in. The outside diameter of the tube is D₂ = 2.8 in. and its wall thickness is t₂ = 0.115 in. Overall dimensions of the assembly are a = 35 in. and b = 11 in. The allowable shear stresses for the bronze and aluminum materials are 9800 psi and 8500 psi, respectively. Further, the rotation angle of end B must be limited to a magnitude of 4.2°. Based on these constraints, what is the maximum torque Tg that can be applied at end B? Fixed End plate plate di TB Rod (1) D₂ Answer: TB = A Tube (2) a lb-in b B
