The shaft as shown in the figure is supported by bearings at A and B. The bearings exert only vertical reactions. The pulley wheel on the end of the shaft applies a vertical force F = 49.4 kN. What is the max bending moment in the shaft? Input your answer as a value only in kNm to one decimal place without +/-sign. 250 mm F 800 mm- B

How do you find the point of application?

(b) Find the natural frequencies and mode shapes. (c) Calculate the natural frequencies and mode shapes with m₁ = m2 = 2 kg and k₁ = k2 = 3000 N/m. You can just use the formula you obtained in (b).

Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N. Calculate the following: (i) (ii) (iii) (iv) The effort force (FEffort) necessary to lift and hold a load of 2000 N. The ideal mechanical advantage…
