- Many years ago, automobiles were manufactured to be as rigid as possible, whereas today’s autos are designed to crumple upon impact. Why?A rain gutter is to be constructed from a metal sheet of width 30 cm by bending up one-third of the sheet on each side through an angle 0, as shown in the figure. How should 0 be chosen (in radians) so that the gutter will carry the maximum amount of water? - 10 cm → 10 cm → 10 cm 0 = 0.5235 X radians Need Help?

- Create a simple balance using a ruler as the balance beam and a pencil as the fulcrum. Put 2 nickels stacked together on one side of the ruler and a single nickel on the other side so that the ruler is balanced.

- A plank is hung from the ceiling by a rope attached 3 meters from one end. The plank is 8 meters long. A 25 kg can of paint is placed 25 meters from the long end of the plank. Wanting to not spill the paint, where should you place a 55 kg sandbag so as not to tip the can? Assume the plank is massless.What would happen if you removed the brass weight on the left? If the meter stick is not balanced, what could you do to rebalance it (without just putting the brass weight back onto the meter stick)?50 300g 10 10 25 cm 3) A kinetic sculpture consists of two rods of negligible mass, each suspended 10 cm from their ends. The longer rod has a length of 50 cm and the shorter has a length of 25 cm. If the square mass is 300 g, then what must the triangular mass and circular masses be to achieve equilibrium?
