g Replace the two forces acting on the frame by a wrench. Write both the force R and the moment M of the wrench as vectors and specify the coordinates of the point P in the y-z plane through which the line of action of the wrench passes. Note that the force of magnitude 200 N is parallel to the x-axis.

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
