What is the difference between a bolt and a stud?
Expert Solution & Answer
To determine
The difference between a bolt and a stud.
Explanation of Solution
Bolt:
A rod that is threaded at one end and has a head on the other end is called a bolt. It is generally used along with a nut and a washer if required. It is used to form a temporary joint which can be removed and replaced at any time.
Stud:
A stud is a rod that is threaded at both the ends generally a coarse thread at one of the end and a fine thread at other and with no head. The coarse threaded end is fastened to the casting whereas the fine threaded end is screwed to a nut to hold the parts together. It is used mostly when the length isn’t known until the installation is started.

The 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)?
The 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.

- 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%.
