Problem 4 Member A is a steel rod with circular cross-section. The modulus of elasticity is 29000 ksi. Member B is very stiff compared to Member A, so ignore its deformations. a. Set up the virtual force system for vertical displacements DEAD 20K LIVE 10 k at Node 2. Determine the minimum diameter of rod that can be used if the deflection due to live load cannot exceed 0.5 in Assume that rods are available in 1/8 in. increments, such...

Homework Problem H 7.E Consider the truss shown below with the loading on joints D, K, S and U. Given: Find: For this problem: a) Determine the external reactions acting on the truss at supports A and H b) Identify all zero-force members in the truss. c) Determine the load carried by members BC, CJ and MN. Identify each member as either being in tension, in compression or carrying zero load. For this problem, use the following parameters: h 30...

Designing a truss bridge This lab involves the design of a truss bridge, which is a Pratt truss and should be designed to handle the loads shown in Fig- ure l (1 kip = 1000 lb). Note that the loads are the same on each of the two trusses for the bridge, so what is in Figure 1 is only half the loading on the bridge. Your job is to develop an optimal design for the bridge, Figure 1. Schematic...

The below truss is made from three bars of the same steel material, all of which have circular cross sections with different diameters. The Young modulus of steel is E= 200 GPa, and yield stress of steel is Gyöeld=200 MPa (in both tension and compression). The force P=7 kN is applied at point C as shown (see Figure 4). All bars are pin connected at their ends. (a) Determine the minimum diameter of the bars so that buckling will not...

The truss is to be analyzed assuming the two loads shown are each 80 kips. By analyzed I mean that reactions at supports are to be determined and the forces (magnitude and sense) acting internally in each member are to be determined. Once forces are known, the members are to be "designed" -that is, the cross sectional area required determined-based on the following...

use following to solve
3) Using an order of magnitude method (Hill), estimate the TCI in year 2006 dollars for a grass-roots plant with 100,000-lb annual production using an order-of-magnitude method based on a 10,000-lb annual production. The plant contains three 1200-ft/min centrifugal fans, five 1500-ft/min centrifugal blowers, seven 100-ft' centrifugal separators, and two 100-ft shell-and-tube heat exchangers. You may assume all materials are carbon steel, the materials handled are primarily solid, and that this plant construction is done fully...
