An orthogonal cutting operation is being conducted with the following parameters: width of cut

=1mm; depth of cut = 0.1mm; shear stress =120 MPa; and coefficient of friction, μ=0.9.

a) Generate a smooth plot of both cutting (Fc) and thrust (Ft) forces versus the rake

angle (α). The plot should be from 0 to 60°. Equation 8.20 can be used to define

the relationship between different angles.

b) Using a different lubricant, the coefficient of friction has changed to 0.3. Generate

another plot with the new value and comment on the results.

An irrigation canal with trapezoidal cross-section has the following elements: bottom width = 2m, depth of water = 0.9m, side slope 1.5H to 1V, slope of canal bed = 0.001, n = 0.025. The canal will serve clay-loam rice land. What is the hydraulic radius in meters? What is the mean velocity in m/s? If the canal will serve a clay-load rice land, determine the area in hectares it can serve if the duty of water per hectare is 3L/s.
