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?

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
A mechanical press is used in a forging operation of a 13.5mm in diameter cylinder. The press is powered by a 26.4kW motor at a velocity of 308 mm/s. The yield stress is 104MPa and the coefficient of friction is 0.249 a) Determine the maximum force that can be exerted in this operation. b) If the cylinder is forged to a diameter of 28.928.9 mmmm, determine the final height of the cylinder.

An 80 mm diameter shaft rotates at 2500 rpm in a cylindrical bearing and is subjected to vertically downward force of 4.0 kN at the bearing. When the power is lost to friction is 1.5 kW. Calculate a) the friction torque and b) the Cefficient of friction between the bearing and shaft.
A company has a contract to build a sewer in a nearby province, it must dig a ditch 2m wide, 1m deep, and 2000m long. Laborers are available at P 120/day for an 8-hr day work and can dig at an average of 0.5 cu-m per hr. A ditchadigging machine maybe rented at a cost of P 1,500 a day for all the time it is in use or in transit. One day would be required for transporting the machine one way. Freight cost would total P 4,000. The machine operator would be paid P350/day including travel time for two days. If the machine is used, three laborers are needed. The ditch digging machine can excavate 1 cu-m in 6 min. All workers and machine rentals must be paid on full 8-hr a day basis. What would you recommend and by how much it must cost?

d) A leather round belt transmit power from small pulley rotates 1200 rpm. The diameter of small pulley is one third of the diameter big pulley. The center distance between the pulleys is twice the diameter of big pulley. The stresses in the belt should not exceed 2 MPa and belt density is 950 kg/m?. Due to the friction of rotation, the ratio tension on the tight side to the slack side is 2:1 and coefficient of friction is 0.35. For design requirement, the ratio of diameter leather round belt to diameter of small pulley is 1:18. Determine, i) Contact angle. i) Diameter belt. iii) Belt tension. iv) Torque.
