In Orthogonal Cutting Model, why chip thickness after cut is greater than chip thickness before cut?

Please help solve this problem!!

What is the external virtual work?

3- Consider the precedence relationship between the activities of an assembly line. Knowing that the cycle time (T) of the assembly line is 10, then: a) Show the activities are assigned to the work station? (Note that you must show which activities are assigned to which stations. Do not give a number of workstations)  b)  Calculate efficiency and smoothness indices.

Machine setup steps should be stated in bullet points for ease.
