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?
Mechanical Engineering The fatigue strength limit Sn (n = 106) of a steel part is 112 MPa and its ultimate tensile strength (Sy) is 385MPa. Adopting Ct = 1, and S103 = 0.9 * Su* Ct, determine: (Use two decimal places in the answers), (* is multiplication signal): a) The fatigue strength (in MPa) corresponding to a life of 40000 cycles. b) The average life in cycles that this part would last if subjected to an alternating stress of 170 MPa due to bending.

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).

1. For this series of 4 questions, a rider rides in a car that is connected to a 4-m rod, and rotates about the z axis. The rod of negligible mass is subjected to a constant couple moment of M, and the engine of the car supplies a traction force of F. Neglect the size of the car. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 3) If the rod is subjected to a constant couple moment of M = 840 N•m, and the engine of the car supplies a traction force of F=11•TN to the wheels, where t is in seconds, what is the magnitude of the angular impulse from the moment and the force to the car-rider system in kg•m2/s from t = 0 to t= 4.9 s?
