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.

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…

Question number 1

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…

Learning Goal:
To find the acceleration a of a particle of mass m, we use Newton's second law:
Fnet = ma, where Fnet is the net force acting on the particle.
To find the angular acceleration cx of a rigid object rotating about a fixed axis, we can use a
similar formula: Thet = Ia, where Thet = ΣT is the net torque acting on the object and I
is its moment of inertia.
In this problem, you will practice applying this formula to several situations involving
angular acceleration. In all of these situations, two objects of masses m₁ and m2 are
attached to a seesaw. The seesaw is made of a bar that has length 1 and is pivoted so that
it is free to rotate the vertical plane without friction.
You are to find the angular acceleration of the seesaw when it is set in motion from the
horizontal position. In all cases, assume that m₁ > m₂, and that counterclockwise is
considered the positive rotational direction.

Learning Goal:
A column with a wide-flange section has a flange width b = 200 mm , height h = 200 mm, web thickness tw = 8 mm , and flange
thickness tf = 12 mm (Figure 1). Calculate the stresses at a point 75 mm above the neutral axis if the section supports a tensile
To calculate the normal and shear stresses at a point
on the cross section of a column.
normal force N = 2.9 kN at the centroid, shear force V = 4.6 kN, and bending moment M = 4.8 kN • m as shown (Figure 2).
The state of stress at a point is a description of the
normal and shear stresses at that point. The normal
stresses are generally due to both internal normal
force and internal bending moment. The net result can
be obtained using the principle of superposition as
long as the deflections remain small and the response
is elastic.
Part A - Normal stress
Calculate the normal stress at the point due to the internal normal force on the section.
