Chapter 4.12, Problem 6P

Draw an objective tree for the following: If you drive in the state of Florida, you may notice some traffic congestion when crews trim trees on the state roads and freeways. Assume that the Florida Department of Transportation is the client. Usually, branches 6 inches or less in diameter are trimmed. The allowable horizontal distance from the edge of the road to the branches is 6 feet. The material removed from the trees must be collected and removed from the roadside. To reduce the cost of trimming, a maximum of only two workers can be assigned for each machine. The overall cost, which includes equipment and labor must be reduced by at least 25% from present cost. The state claims that the demand for your machines will follow the price reduction—that is, if you are able to reduce the cost by 40%, the demand will increase by 40%. Allowable working hours depend on the daylight and weather conditions.

Task 2:Objects falling downwards experience two types of vertical forces; one due to gravity and the other due todrag.You are interested in finding a design solution to the following problem:A design of a hemispherical parachute for a skydiver with a mass of 80 kg is to be part of further prototypingand structural integrity testing. To safely perform the jump, landing speed should be no more than 5 m/s. Whatis the minimum parachute diameter required to accomplish your test?Assume constant speed and sea-level elevation.
1. In general, what pattern do you notice between the force due to the gravity of the masses and the displacement of the spring? 2. What is the physical meaning of the slope? 3. Using the slope for each spring, what would be the force required to stretch the spring 0.10 m? 4. Using the slope for each spring, what would be the amount of stretch with a 500 g mass hanging on the spring? Ps: pls refer to the graph below
