A company produces two types of components (A and B) whose lengths are normally distributed. Type A components are IID normal with a mean of 67.2 cm and a standard deviation of 1.9. cm, whereas those of type B follow a normal distribution with a mean of 33.2 cm and a standard deviation of 1.1 cm, independently from each other and from type A components. What is the probability that three components of type B have a total length shorter than two components of type A?

6. The coefficient of static friction between the rear wheels of the tractor and the ground is $\mu_s = 0.65$. The engine provides a torque M to the rear wheels. What will happen in this scenario? Will the front wheels lift off the ground? Will the rear wheels slip? How large of a torque would be needed to cause the motion? Assume that the front wheels are free to roll, the tractor weighs 3000 lb and has a center of gravity at G.

13. (10 points) Suppose there is a common resource, like trees in the Amazon rainforest. The private MC of harvesting these trees is a constant, \$C. Assume each tree consumed reduces social benefit twice as much as private benefit. Illustrate graphically the social optimum consumption and private consumption of trees using social benefit, private benefit, and private marginal cost. Suppose harvesting trees becomes easier, reducing the marginal cost. What effect would this have on the harvesting of common property? Will the market failure be larger or smaller?
