Problem:M1.1
You and your friends are on an archaeological adventure and are trying to disarm an ancient trap to do so you
need to pull a log straight out of a hole in a wall. You have 1 rope that you can attach to the log and there are
currently 2 other ropes and weights attached to the end of the log. You
know the force and direction of the ropes currently attached are arranged
as shown below what is the magnitude and direction 'e' of the minimum
force you need to apply to the third rope for the force on the log to be in
direction of line 'a'? What is the resultant force in direction 'a'?

In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )arrow_forward
