Metrology of Screw Threads

Screw threads are a series of ridges having the profile of a helix. This helix profile runs continuously along the length of a uniform solid or a hollow bar of a circular cross-section at periodic intervals. These helix ridges are also formed over a conical bar. These continuous helical ridges are termed threads.

1. Four years ago, an ore-crushing unit was installed at a mine which cost Php81,000. Annual operating costs for this unit is Php3,540. This unit was estimated to have a life of 10 years. The quantity of ore to be handled is to be doubled and is expected to continue at this higher rate for at least 10 years. A unit that will handle the same quantity of ore and have the same operating costs as the one now in service can be installed for Php75,000. This unit will have a useful life of 6 years. A unit with double the capacity of the one now in use can be installed for Php112,000. Its life is estimated at 6 years and its annual operating costs are estimated at Php4,950. The present realizable value of the unit now in use is Php26,000. All units under consideration will have an estimated salvage value at retirement age of 12% of the original cost. Interest rate is 20%. Annual taxes and insurance are 2.5% of the original cost. What would you recommend?

Calculate the capitalized cost of a project that has an initial cost of P 3,000,000 and an additional cost of P 1,000, 000 at the end of every 10 yrs. The annual operating costs will be P100, 000 at the end of every year for the first 4 years and P160, 000 thereafter. In addition, there is expected to be recurring major rework cost of P 300,000 every 13 yrs. Assume i =15%. Calculate it manually, not in excel. Show complete solution and formula used.
