upper leg muscle 9 cm in radius). 2) Don't ever try the acorn diet, its nuts. In the tree diagrammed here, a force of 800 N is exerted at the tip of the limb (equivalent to the weight of "800 apples). The limb is circular in cross-section and 2 m long with a tip radius of 3 cm a base radius of 10 cm. The radius increases linearly from the tip to the base. Plot the tensile stress at the top of the limb along its length. Where along the length would you expect the limb to break? M. X. Lo Y
After years of asking, you finally were allowed to go on a joy ride in your uncle’s 1956 Mercedes-Benz 300 SL. A notable feature of this vehicle is the gullwing door design that opens from a hinge at the top of the car. Unfortunately, you are having so much fun driving the car that you end up submerged in a fresh water lake. You sink to the bottom of the lake, which has a depth of 10 m. For the sake of simplicity, you can model the door as a 1 m × 1 m square plate, inclined at 45° relative to the floor of the lake. Neglect the weight of the door and friction in the hinge. How much force will be required to open the door, assuming you push from its geometric center?
4. Pick three different whole numbers of ounces of beverage for Alice to drink and find her height after consuming each amount. Assume in each case that she starts out 5 feet tall.
7. From measurements taken on the variation of pressure with depth in a liquid, it was found that, on a certain day, 2m below the surface of a given liquid, the absolute pressure was 1.17 x 105N/m², while at a depth of 5m the absolute pressure was 142kN/m². Find a) the relative density of the liquid; b) the atmospheric pressure on the day in question.
1. A thermometer is taken from a room that is 20 °C to the outdoors where the temperature is 5 °C. After one minute, the thermometer reads 12 °C. Use Newton's Law of Cooling to answer the following questions:- (a) What will the reading on the thermometer be after one more minute? (b) When will the thermometer read 6 °C?

Children asked their parent for an ice cream after dinner. They eat their ice cream as long as it does not melt and its structure is solid. The parent drove to buy an ice cream in the grocery store. The ice cream is sold in family sized package. The store keeps the ice cream packages in the freezer until it is sold. The packages are made from polystyrene material and their size is 0.2´0.1´0.07 m3 . The store freezer temperature is kept at -10o C. The ice cream has a solid structure (not melting) as long as its temperature remains below 0o C. The time it takes to reach back from the store is 20 minutes Will the kids eat the ice cream at home? Ice cream properties: k = 2.2 W/mo C, C = 1800 J/kgo C, r = 900 kg/m3 and h = 10 W/m2oC.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
You are to spray an 80-acre field that will be planted to alfalfa with 32 oz/ac Roundup, 1.5 pints/ac of Treflan, and 17lbs AMS/100 gallon spray. If your sprayer is calibrated to apply 10GPA carrier volume and holds 800-gallons how much AMS do you need to add to your sprayer to condition your water, and how many gallons of Roundup and Treflan do you need to add to your sprayer so that you apply the proper rate?
1. Consider the temperature in a composite wall consisting of materials A,B,C which is shown below. Three materials' sizes are exactly equal. Top and bottom side of the wall is well insulated. We assume that thermophysical properties are all constant. Which two of the following are true A) Thermal resistance is largest in material A B) Theral resistance is largest in material B C) Heat is being generated within the wall D) Sign of heat rate is positive E) sign of heat rate is negative 2. Which two of the following are best correct statements for the wall with the temperature distribution shown below: A) The heat flux would be constant at any location in the wall B) It is unclear if heat is being generated within the wall C) Heat does not flow across the centerline D) Everywhere inside the wall, heat flows only to the right( same direction as the x-direction E) If the convection outside the wall is occuring with a normal magnitude of h, then it can be expected that Ts >>…
