2. A 6-m-long pole AB is placed in a hole and is guyed by three cables. Knowing that the tensions in cables BD and BE are 442 N and 322 N, respectively, determine (a) the tension in cable CD, (b) the reaction at A and its x and y component. Ans. a) CD = N 3.15 m b) Rax= 6 m Ray = 2.10 m R = D.

Question 4 a) Each cylinder in a four-cylinder car engine has a bore diameter of 63.53 mm and the stroke for each piston is 175.00 mm. Calculate the cubic capacity of the engine in cm? and calculate the clearance volume per cylinder for a compression ratio, r, of 6.25. b) The bore diameter of each cylinder in a six-cylinder four-stroke internal combustion engine is 32 mm and the stroke of each piston is 125 mm. During testing., the engine runs at 1450 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 2.90 cm and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kN/m per cm. Calculate the mean effective pressure (m.e.p) and the indicated power in kilowatts (kW) developed by this six-cylinder four-stroke engine. Give your answer to 2 decimal c) A hollow connecting rod has an inner diameter of 26.25 mm and is subjected to an axial tensile load of 500 MN. If the maximum allowable stress for this hollow rod…

Youre supposed to find the final pressure so this isnt super helpful. Can you help me with the next steps?
