A concrete block making company is developing an aggregate capacity plan from the following sales forecast for its 6β and 8β concrete blocks shown in the table below. Product Sales Forecasts (Concrete Blocks) 1st Quarter 2nd Quarter 3rd Quarter 4th Quarter 6β Block 2,000 1,500 1,600 1,800 8β Block 1,200 1,000 800 1,000 Ample machine capacity exists to produce the forecast. Each 6β concrete block takes an average of 20 labour-hours while each 8β concrete block takes an average of 15 labour-hours. a) Compute the aggregate number of labour-hours in each quarter. b) If the plant works the same number of days in each quarter, 13 five-day weeks on a single shift, how many workers will be required in each quarter? c) It costs $1,000 to hire a worker and $500 to lay off a worker, and inventory carrying cost is $100 for each 6β concrete block and $100 for each 8β concrete block (this means that if one 6β concrete block were held in inventory for a year, it would cost $100 for finance charge, insurance, warehousing expense, etc.). The plant works the same number of days in each quarter, 13 five-day weeks. Assuming that the quarterly demand pattern repeats from year to year, compute the cost of each of the following two aggregate plans for next year: i. Chase strategy plan. Beginning inventory in this plan is zero for both types of concrete blocks. ii. Level strategy plan. Beginning inventory in this plan is 275 for 6β concrete blocks and 200 for 8β concrete blocks.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180Β°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in Β°r, as the water flows through the pump.
