Learning Goal:
To use transformation equations to calculate the plane state of stress in a rotated coordinate system.
The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are
given in one coordinate system (Figure 1), the equivalent stresses in a rotated coordinate system (Figure 2) can
be calculated using a set of transformation equations. Both sets of stresses describe the same state of stress.
In order to use the transformation equations, a sign convention must be chosen for the normal stresses, shear
stresses, and the rotation angle. For the equations below, a positive normal stress acts outward on a face. A
positive Try acts in the positive y-direction on the face whose outward normal is in the positive x-direction. The
positive direction for the rotation is also shown in the second figure.
The stresses in the rotated coordinate system are given by the following equations:

Learning Goal:
To understand the concept of moment of a force and how to calculate it using a scalar
formulation.
The magnitude of the moment of a force with a magnitude F around a point O is defined
as follows:Mo = Fdwhere d is the force's moment arm. The moment arm is the
perpendicular distance from the axis at point O to the force's line of action.

Part A
A stool at a restaurant is anchored to the floor. When a customer is in the process of sitting down, a horizontal force with magnitude F₁ is exerted at the top of the stool support as shown in the figure. (Figure 1)
When the customer is seated, a vertical force with magnitude F2 is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is M₁ = 140 lb-ft, what is the
maximum height do that the stool can have if the magnitudes of the two forces are F₁ = 65.0 lb and F₂ = 140 lb ? Assume that moments acting counterclockwise about point A are positive whereas…
