Chapter 12, Problem 5P
Your brother is opening a skateboard shop. He has created a sign for his shop made from a uniform material and in the shape shown in Figure P12.5. The shape of the sign represents one of the hills in the skateboard park he plans on building on land adjacent to the shop. The curve on the top of the sign is described by the function y = (x − 3)2/9. When the sign arrives in his shop, your brother wants to hang it from a single wire outside the shop. But he doesn’t know where on the sign to attach the wire so that the bottom edge of the sign will hang in a horizontal orientation. He asks for your help.

You have three identical, uniform, square pieces of wood, each with side length L. You stack the three pieces of wood at the edge of the horizontal top of a table. The first block extends a distance L/4 past the edge of the table. The next block extends a distance L/4 past the edge of the first block, so a distance L/2 past the edge of the table. The third block extends a distance L/4 past the edge of the block beneath it, so 3L/4 past the edge of the table. The stack is unstable if the center of mass of the stack extends beyond the edge of the table. Calculate the horizontal location of the center of mass of the three-block stack.

You are tasked with creating a "flexible" spreadsheet for your employer that will calculate the total volume of several cylindrical storage tanks.

- It’s an arm day at the gym and all the free weights and machines are taken. You don’t have much time to squeeze in your workout before your next class. Desperate to get your reps in, you see a pile of Therabands (the giant rubber bands used for physical therapy). The bands are 100 mm wide and 1.5 mm thick. You sit down to do some bicep curls with the Theraband tied to rack 60 cm away from your hand and your hand is 80 cm from the floor. However, a single length of the Theraband is too easy to curl, so you end up wrapping it around your hand twice (i.e. you are stretching 4 lengths of Theraband when you do your reps). Your hand starts out 60 cm from the Theraband anchor point before your do your bicep curl (i.e. no stress on the band, band has no slack). You contract your bicep until your forearm is parallel with the floor and hand in the position below and hold static equilibrium.
