A composite beam consists of a steel I - beam with a concrete slab on top. The yieldstrength of the steel is 250 MPa, and the compressive strength of the concrete is 40 MPa. If thearea of the steel section is 3000 mm^2 and the area of the concrete section is 50000 mm^2, calculate the load - carrying capacity assuming the composite section reaches its full plasticmoment

Two angles joined by 7/8-in. rivets form a steel tension member. The gross area of the member is 6 sq. in. and the thickness of the material is 3/8 in. The net area of the member may be found by allowing for one rivet hole in each angle. What is the maximum load that may be carried safely by the member if the allowable stress is 16,000 psi. a. 73,000 lb b. 48,000 lb c. 99,000 lb d. 84,000 lb

A company owns two adjacent builds, and in each building, there is one piece of equipment that operates separately from one another. Based on past history, equipment 1 is expected to break down 7 times a year, with a variance of 3, and costs $600 per breakdown. equipment 2 is expected to break down 9.2 times per year, with a variance of 2.1, and costing $245 per breakdown. 1. What is the company’s expected cost for equipment breakdowns? 2. What is the variance of the breakdown cost? Provide set up of work to compare notes.
