The bracket shown in Figure 3-20 is part of an aircraft assembly. It is important that the bracket be as light in weight as possible. To reduce weight, equal-sized holes are drilled the bracket. The bracket weighs 5.20 kilograms before the holes are drilled. After 14 are drilled in the bracket, the weight is reduced by 1.26 kilograms. How many more the same size must be drilled to reduce the weight of the bracket to 3.40 kilograms? A home remodeler purchases hardware in the quantities listed in the table in Figure The remodeler is able to reduce unit costs by quantity purchase. For a certain kitchen remodeling job, the following quantities of hardware are used: 5 boxes of cabinet hinges 8 1/2 boxes of drawer pulls 7 boxes of cabinet knobs 1 1/4 boxes of hanger bolts 3 boxes of magnetic catches Find the total hardware cost that should be charged against this job. Series electrical circuits are shown in Figure 3-22. In a series circuit the total circuit resistance (R_T) equals the sum of the individual resistances. R_T = R_1 + R_2 + R_3 + R_4 + R_5 Current in the circuit (I) equals voltage (E) applied to the circuit divided by the total resistance (R_T) of the circuit.
