1.10 Figure 1.24 shows a special spanner used to tighten screwed components. A torque is applied at the tommy- bar and is transmitted to the pins which engage into holes located into the end of a screwed component. (a) Using the data given in Fig. 1.24 calculate: (i) the diameter D of the shank if the shear stress is not to exceed 50 N/mm², (ii) the stress due to bending in the tommy-bar, (iii) the shear stress in the pins. (b) Why is the tommy-bar a preferred method of applying the torque? 26 26 5 [C.G.] [9.14 mm; 254.6 MN/m²; 39.8 MN/m².] Mechanics of Materials 50N force applied at a distance of 25 mm from both ends of tommy bar Q Fig. 1.24. 05 100
Calculate the capitalized cost of a project that has an initial cost of P 3,000,000 and an additional cost of P 1,000, 000 at the end of every 10 yrs. The annual operating costs will be P100, 000 at the end of every year for the first 4 years and P160, 000 thereafter. In addition, there is expected to be recurring major rework cost of P 300,000 every 13 yrs. Assume i =15%. Calculate it manually, not in excel. Show complete solution and formula used. Please write it in a paper in order for us to understand. Don't type it. Thank you! ANS. P 4,281,935.95
2.) An automobile lift raises a car weighing 3000 lbf, 6 ft off the shop floor (Fig. 2-12). Assuming the lift itself weighs 500 lbf and th at friction is negligible , what is the worknecessary to raise the car in ft-Ibf and m-N ?
A stringer of tennis rackets has found that the actual string tension achieved for any individual racket will vary as much as 6 pounds per square inch from the desired tension set on the stringing machine. If the stringer wishes to string at a tension lower than that specified by a customer only 5% of the time, how much above or below the customer's specified tension should the string set the stringer machine

Two blocks weighing 600lbs and 400lb shown in Figure 3 are to be moved to the right by the blockweighing W, lb. The pulleys are assumed to be frictionless while f = 0.10 for the blocks. Determine theweight W in pounds (lbs) to start the system.
4) One measure of the scale of a process is its throughputs of fuel or other input raw materials, e.g., lbs of coal per hour. Compare the coal throughputs for a small-scale experiment that uses 10 mg of coal in 6 seconds, and a single boiler in a large commercial-scale central-station electric generating plant. Assume: the commercial facility has a total output of 1,020 MW e supplied by three boilers of equal capacity; the boiler has a heat rate of (8,980 Btu th /hr)/(kW e ) based on fuel HHV, and fires coal with a gross heating value (i.e., HHV) of 14,000 Btu th /lb.
#7) You use a rope to apply a horizontal force of 63 N to pull a box a distance 7 m across the floor at constant velocity in 5 secons, and a frictional force of opposes this motion. What is the power dissipated as heat by the frictional force? F = 63 N fr X1 = 7 m
A multi-cylinder engine is to run at a speed of 600 r.p.m. On drawing the crank-effort diagram to scale of 1 cm 2452.5 N-m and I cm 30°, the areas above and below the mean torque line in sq.cm. are as follows: +1.6, -1.72, +1.68, -1.91, +1.97 and -1.62. The speed is to be kept within ±1% of the mean speed of the engine. Calculate the necessary moment of inertia of the flywheel. Determine the suitable dimensions of a rectangular flywheel rim, if the breadth is twice the thickness. The density of the cost- iron is 725 gm/cm' and its hoop stress is 588.6 N/cm2. Assume that the rim contributes 92% of the flywheel effect.
