Chapter 5, Problem 5QAP
To determine
(a)
The effect of weight of the book when reduce the applying force to the book in the same spot on the wall.
Expert Solution
Answer to Problem 5QAP
The weight of the book is not changed.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
So the magnitude remains constant. Therefore weight stays the same.
Conclusion:
The weight stays the same.
To determine
(b)
The effect of the normal force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Expert Solution
Answer to Problem 5QAP
The normal force of the wall on the book decreases.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
When applied force is reduced the normal force decreases.
Conclusion:
The normal force of the wall on the book decreases.
To determine
(c)
The effect of the frictional force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Expert Solution
Answer to Problem 5QAP
The frictional force of the wall on the book is not changed.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
So the weight of the book is constant. Therefore the frictional force of the wall on the book stays same.
Conclusion:
The frictional force of the wall on the book stays same.
To determine
(d)
The effect of the maximum static frictional force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Expert Solution
Answer to Problem 5QAP
The maximum static frictional force of the wall on the book deceases.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
When F reduces R decreases. Since
Conclusion:
The maximum static frictional force of the wall on the book deceases.

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius
p. 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 )

Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens.
