Question & Answer

A company produces a certain part whose most important dimension is 37.50 ±0.025 in. If the tolerance is exceeded, the customer will return the part to the manufacturer at a cost of $200 in rework and replacement expenses. (a) Determine the constant k in the Taguchi loss function, Eq. (42.13). (b) The company can add a finish grinding operation that will allow the tolerance to be reduced to ±0.010 in. Using the loss function from part (a) what is the value of the loss associated with this new tolerance?

1. Do poor people gain more from a cut in income tax with an elastic or an inelastic supply of labour? Is the supply of unskilled workers likely to be elastic or inelastic? 2. Draw two diagrams like Figure 11.13, one with a steep demand curve and one with a shallow demand curve. How does the elasticity of demand affect the incidence of the income tax?

A turning operation is made with a rake angle of 10°, a feed of 0.010 in/rev and a depth of cut = 0.100 in. The shear strength of the work material is known to be 50,000 lb/in2 , and the chip thickness ratio is measured after the cut to be 0.40. Determine the cutting force and the feed force. Use the orthogonal cutting model as an approximation of the turning process.

A laser triangulation system has the laser mounted at a 35° angle from the vertical. The distance between the worktable and the photodetector is 24.0000 in. Determine (a) the distance between the laser and the photodetector when no part is present and (b) the height of a part when the distance between the laser and photo-detector is 12.0250 in.

Identify some materials that possess a noncrystalline structure.

Caplets are used to support a sand core inside a sand mold cavity. The design of the caplets and the manner in which they are placed in the mold cavity surface allows each caplet to sustain a force of 10 lb. Several caplets are located beneath the core to support it before pouring; and several other caplets are placed above the core to resist the buoyancy force during pouring. If the volume of the core = 325 in.3 , and the metal poured is brass, determine the minimum number of caplets that should be placed (a) beneath the core, and (b) above the co

Your accounts receivable clerk, Mitra Adams, to whom you pay a salary of $1,500 per month, has just purchased a new Acura. You decided to test the accuracy of the accounts receivable balance of $82,000 as shown in the ledger. The following information is available for your first year in business. (1) Collections from customers $198,000 (2) Merchandise purchased 320,000 (3) Ending merchandise inventory 90,000 (4) Goods are marked to sell at 40% above cost Instructions Compute an estimate of the ending balance of accounts receivable from customers that should appear in the ledger and any apparent shortages. Assume that all sales are made on account.

A sheet-metal part 3.0 mm thick and 20.0 mm long is bent to an included angle = 60° and a bend radius = 7.5 mm in a V-die. The metal has a yield strength = 220 MPa and a tensile strength = 340 MPa. Compute the required force to bend the part, given that the die opening dimension = 15 mm.

Matt and Lori recently were divorced.  Although grief stricken, Matt was at least partially comforted by his monthly receipt of $10,000 alimony.  He was particularly excited to learn from his friend, Denzel, that the alimony was not taxable.  Use an available tax service to determine if Denzel is correct.  Would your answer change if Matt and Lori continued to live together?
