Due to the changes in the Biology sequence of courses, there
are some changes to the BME curriculum. For the class of 2017
and on, BME students will take Bio 1 and the lab (119:115 and
119:117). If they choose to also take Bio 2 (119:116), it will count
a

Worked with:_
1. You are designing the command module for a NASA mission and you have to
figure out where on the module are zC and zCM (the centroid and center of mass
height, respectively). You decide to model it in pa

Vectors
You can find the component of one
vector that acts in the direction of
another vector by taking the scalar
dot product of the two vectors
Also referred to as the projection of one
vector onto another

Worked with:_
50 points.
1. Everyone had difficulty with the moment question on the exam, so you
will all get to do it again here. You have the answers written in your

Vectors
To add vectors you essentially join
the head of one vector to the tail of
the other while retaining the
magnitude and direction of the
vectors
Or, break the vectors into their x, y,
and components and add them
together

Moments
To find net moment, sum individual
components relative to reference
coordinates
In statics, this sum always equals
zero!
Mx =My = Mz = 0
Fx = Fy = Fz = 0
