A company has an annual demand for a product of 1000 units, a carrying cost of $20 per unit per year, and a setup cost of $100. Through a program of setup reduction, the setup cost is reduced to $10. Run costs are $2 per unit. Calculate:
a. The EOQ before setup reduction.
b. The EOQ after setup reduction.
c. The total and unit cost before and after setup reduction.
Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 23kW of shaft power. The free surface of the upper reservoir is 46m higher than that of the lower reservoir. If the flow rater of water is measured to be 0.03m^3/s d..
The maximum modulus of elasticity for a copper crystal is 195 GPa. What tensile stress is required along the corresponding crystallographic direction in order to increase the interatomic separation distance by 0.09% ?
Identify a cost-effective rectangular duct section with an equivalent pressure loss that has a side depth of 20 in.
A body is dropped on the moon (g 1.62 m/s2 ) with an initial velocity of 12 m/s. By using option 2 variables, Eq. (5.11), the ground impact occurs at t** 0.34 and S** 0.84.

determine Wf and the force of attraction that acts to attempt to reduce the gap at t = 1 second. Where is the energy of the coupling field stored in this system?
A 90-N force is applied to the control rod AB as shown. Knowing that the length of the rod is 225 mm, determine the moment of the force about point B by resolving the force into horizontal and vertical components.
