(The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of oxygen-16 is $2.66 \times 10^{-26}$ kg, and they are both singly charged and travel at $4.95 \times 10^6$ m/s in a 1.5 T magnetic field.

A beam is loaded and supported below. Assume that EI is constant for the beam. (a) Determine the reactions at supports A and C. (b) Determine the deflection in the middle of the span (@ point B). Hint: you can either use integration method, or superposition method. You ONLY need to use one method. If you use superposition method, you can refer to the deflection of cantilever beam due to concentrated moment M in the Appendix C - Beam 9 and Beam 7 (textbook page 855.)

Walter's Wiggles produces and sells bobbleheads. The selling price of each collectible bobblehead is $80, and the variable cost per bobblehead is $48. Fixed costs are $4,000. Using this data, answer the following questions: P1. What is the break-even point in units and dollars? P2. Create a contribution margin income statement at break-even. P3. If Walter sells 150 bobbleheads, what will be his income? P4. If Walter has a contribution margin of $6,400, how many bobbleheads did he sell? P5. If Walter's fixed costs change to $4,640, how many additional units will he need to sell to break-even?
