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…

Learning Goal:
To use equilibrium to calculate the plane state of stress in a rotated coordinate system.
In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero.
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 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress.
The stresses σx′and τx′y′ can be found by considering the free-body…

This problem maps back to learning
objectives 1-4 & 8.
Consider the particle attached to a spring shown below. The particle
has a mass m and the spring has a spring constant k. The mass-spring
system makes an angle of 0 with respect to the vertical and the
distance between point 0 and the particle can be defined as r. The
spring is unstretched when r = l.
