In a Wisconsin dairy, the number six has special significance for the dairy workers. When they prepare the cartons of milk for shipping, they put six cartons in a box, six boxes in a crate, six crates in a flat, and six flats on a pallet. 6 cartons = 1 box 6 boxes = 1 crate 6 crates = 1 flat 6 flats = 1 pallet So that they know how many more cartons of milk are needed to complete a pallet, the dairy workers have developed a system for describing the status of a pallet at any point during the packing process. Their notation is: (# of flats)(# of crates)(# of boxes)(# of cartons) For example, a 4312 is a partially filled pallet that has 4 flats, 3 crates, 1 box and 2 cartons on it. Using this notation, 10000 is a completed, ready-to-ship pallet. (a) While you were on a field trip to the dairy, you counted 321 cartons of milk that were ready to be placed on a pallet. How would you represent that amount of cartons in the dairy's notation? Show all your work. (b) As you were walking out the door, you heard someone yell, \"I have a 2045 that needs filling!\" How many milk cartons, in dairy notation, do they need to complete the pallet? Show all your work.

Based on the distortion energy theory, determine the factor of safety, n, for the stress element at A of the member shown in the figure. This bar is made of AISI 1015 hot-rolled steel and is loaded by the forces F = 0.4 kN, P = 4 kN, and T = 31 Nm. Give your answer to 3 significant figures. Hints: The normal stress has 1 component and the torsional stress has 2 components. Be sure to convert units to m and N, and ensure the same units of yield strength and maximum allowable stress when calculating n! 15-mm diameter Table 3-2 Formula for Maximum Transverse Shear Stress from V0 34 Table A-20 Designation ASTM Minimum Tensile Strength and Yield Strength [The strengths listed are estimated ASTM minimums.
