A) A steel rod (C-D) of diameter 1" is attached to the ceiling at C and is used to hold up the middle end of a 2" square steel bar (A-B), which is pinned to the wall (at A). This structure is used to support the construction of a new atrium in the lobby of an existing building. If the applied load on beam (A-B) is as shown in Figure 1, determine the internal load carried by the steel rod...
Sut = 80 ksi, Sy= 60 ksi, Si = 40 ksi, q=0.85 (notch sensitivity), steel E = 30e6 psi Remember we use Modified-Goodman for all calculations A 1-inch diameter rod that is 8 inches long has a bearing at one end and another bearing at 6 inches (treat bearings as simple supports). A vertical load is applied at the end of the overhanging rod and a torque is transmitted through the length of the rod. (Fmax = 100 lbf Tmax...
<HW #6 Problem 4.72 ① 2 of 3 Review Part A The two cylindrical rod segments shown in the figure below (Figure 1) are fixed to the rigid walls such that there is a gap of 0.01 in between them when Ti = 60°F. Each rod has a diameter of 1.25 in. Take a = 13(10-)/F, E2 = 10(103) ksi, (oyal = 40 ksi, acu = 9.4(10-/F, (OY)cu - 50 ksi, and Ecu = 15(10) ksi Determine the average normal...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
