# Hwk video solutions

Homework H.8.A
Homework H.8.B Note: The solution for 8B considers 500ft-lb moment in opposite direction than what is actually given in the question. So actual final answer is different from the one obtained in the video.

Homework H.14.A Note: At 7:05 minutes in the video, it should be negative sign instead of the positive sign used. The final answer for Y_c changes accordingly.

Homework H.21.A
Homework H.21.B

Homework H.22.A Note: Please note the following errors in the video. (1.) At 10:55 minutes in the video, F_x equation at joint E should have F_EH instead of F_BH. (2.) At 14:00 minutes in the video, the equation for F_BH (which is supposed to be F_EH) should be multiplied by a negative sign on RHS.
Homework H.22.B Note: At 11:49 minutes in the video, it should be F_BE*sin(theta) instead of F_BE*cos(theta) given in video.

Homework H.24.A - Note:  At 9:15 minutes, it should be -F_RS*(2h) instead of + used in the video.
Homework H.24.B - Note: 1. AB and KH are also zero force members but not indicated in the video. 2. At 5:58, F_DB=(h/b)*F instead of F_DB=(b/h)*F as given in video.

Homework H.29.A
Homework H.29.B

Homework H.33.A Note: At 04:50 minutes, C_y = -W instead of what is given in the video. All the answers change accordingly.
Homework H.33.B

Homework H.36.A - Beginning at 4:00 minutes, Oy=9wd/4 should be used instead of 7wd/4 as done in the video. This is going to change all the final answers.
