4. The press in Figure 4 is used to crush a small rock at E. The press comprises three links ABC,
CDE and BG, pinned to each other at B and C, and to the ground at D and G. Sketch free-body
diagrams of each component and hence determine the force exerted on the rock when a vertical
force F = 400 N is applied at A.

- 1. The shaft AD in Figure 1 supports two pulleys at B and C of radius 200 mm and 250 mm respectively. The shaft is supported in frictionless bearings at A and D and is rotating clockwise (when viewed from the right) at a constant speed of 300 rpm. Only bearing A can support thrust. The tensions T₁ = 200 N, T₂ = 400 N, and T3 = 300 N. The distances AB = 120 mm, BC = 150 mm, and CD120 mm. Find the tension 74 and the reaction forces at the bearings. A T fo Figure 1arrow_forward5.

Figure 3arrow_forwardA pipeline engineer is considering alternative natural gas pipeline routings. The first route is mostly over land and the second is primarily undersea. Both pipelines will need some valve and fitting replacements in year 25. Cost data for each route is shown in Table P2.21. Notice that the undersea route has a higher initial cost due to higher installation costs and extra corrosion protection for the pipeline. However, the undersea route has cheaper security and maintenance costs which substantially reduces annual costs. The MARR for the project is 15%. Determine which route should be pursued based on a present worth analysis.arrow_forward
- The state of stress at a point is σ = -4.00 kpsi, σy Tyz = 8.000 kpsi, and T₂ = -14.00 kpsi. What is the maximum shear stress for this case? The maximum shear stress is kpsi. = 16.00 kpsi, σ = -14.00 kpsi, Try = 11.00 kpsi,arrow_forwardThe initial cost of a proposed heat recovery system is $375,000. The annual operation andmaintenance costs are projected to be $12,000. The salvage value of the system at the end of itsuseful life (projected to be 30 years) is $60,000. The annual savings in fuel costs resulting fromthis system are estimated to be $55,000 per year.a. Assuming annual compounding, determine the rate of return for this heat recovery system.b. If management has set the MARR to be 15% for a heat recovery system like this, what is themaximum initial cost that can be spent on the system (assuming that all other costs and incomesare the same)?arrow_forwardThe initial cost of a machine for a production facility is $225,000. The machine is expected tolast for 10 years with no salvage value. The company’s tax rate is 49% and SLD is used todepreciate the machine. For this type of depreciation, the tax life of the machine is considered 8years and its salvage value is $5,000. The after-tax rate of return is 14.3%. Determine the uniformannual before-tax cash flow.arrow_forward
- Three alternatives are being considered for an air cleaning system. All three systems have a lifeof 10 years with no salvage value. System A has an initial cost of $29,000. During the first fiveyears of operation, the annual costs to operate system A are $5,000. During the second five years,the annual cost of system A increases to $16,000. System B has an initial cost of $43,000. Theannual cost to operate system B is $4,000, however, after the first year, this cost increases by$1,600 per year. System C has an initial cost of $58,000 with an annual cost of $2,400. System Crequires two upgrades: one during year 4 which costs $6,000, and the other during year 8 whichcosts $3,000. The MARR for this project is 17%. Determine which air cleaning system should beinstalled based on an economic analysis.arrow_forwardShow all work as much as you can and box out answersarrow_forwardShow as much work as possible and box out answers pleasearrow_forward
