The cam lobe from a car’s engine, shown below in Figure 3, is cut from a steel plate. The upper half of its profile is described by the function y(x)=1.5-1.5x4,where y is the vertical height in centimetres above the x-axis. The x-axis runs from x=-1cm to x=1 cm, with the origin at its centre. The lower half of the profile is a semicircle of radius 1 cm. Figure 3 Cross-section of the camshaft in question 3 a. By splitting the area of the cam above the x-axis into a...
