Due Thursday, November 10th at the beginning of class
1. (10 points) Assemble cfw_Pf and [S] using Code number method. Executive summary
give cfw_Pf and [S].
E = 29,000 ksi
I =_- 310 in.4
2. (20 points) Solve using MDM de
Wx=500*cos(22.62)*sin(22.62)=177.516lb/ft
=0.177516k/ft=35.503lb/in
Wy=500*cos(22.62*cos(22.62)=426.035lb/ft
=0.426035kip/ft=14.793lb/in
Not required for working of the
problem. This is just a cross
check!
