Important instruction: These questions use the last three-digit value (L3D) of individual student matrix numbers. For example, if the matrix number is CD180264 then the L3D value is 264 (since the last three digits is 264). Some data require multiplication of the L3D value, for example, 10(L3D) means 10 x L3D

Scenario
You are assigned a role as a mechanical engineer for a vehicle design manufacturing company. Your
department has a software to perform numerical differentiation and integration. To be able to verify the
results of using the software and validate these results, your department manager has asked you to
analytically perform some tasks to validate the results generated by the software.
Q: is the last two digits of your student Id number. If your number is (20110092) then Q=92.
P: is the last digit of your student Id Number. If your number is (20110092) then P=2,
If that digit equals zero then use P=1. Example: If your number is (20110040) then P=1.

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…

You are currently in a stable orbit 9000 km
(1km=1000m) from the center of planet Proxima
Centauri B.
According to the calculations done by NASA, Planet Proxima Centauri B has
a mass of approximately 7.6x10^24kg.
Based on fuel consumption and expected material aboard the ship, your
colony ship lander has a mass of approximately 1.1x10^5 kg.
1. Using Newton's Law of Universal Gravitation, determine what the force of
gravity on your ship at that orbit be using the early measurements
2.Using Newton's second law determine the acceleration of your lander due
to gravity
3.Upon arrival, you measure the actual force of gravity to be 6x10^5 N,which
