Question description

I have couple problems that i need to be solved. I am going to post the problems here, and attach a file to solve the problems. without the file you can't solve any problem. in the problems it says that this problem refer to digram in the file, so just go check the file.

watch out the numbers are different than the ones in the file.

Hello, am not yet done, I will be uploading a final sooner

Problem 5 (4 pts) Refer to Hibbeler problem 3.19 for: Use 2.2 Mg, 1.3 Mg, 0.5 Mg, 3.9
Mg, 7.9 m, 3.2 m, 7.6 m and 14.1 m instead of 2 Mg, 1.5 Mg, 0.5 Mg, 6 Mg, 7.5 m, 4 m,
9.5 m and 12.5 m.
(ππ)π΄ = ________________ (ππ)π΅= ________________
Solution
(ππ)π΄ =(ππ)π΅=οFd

Resultant moment at point A
β ππ΄ = 0
ππ΄ = [(2.2 β 9.81)(14.1) + (1.3 β 9.81)(7.6) β (0.5 β 9.81)(3.2) β (3.9 β 9.81)(7.9)]
= [304.31+89.47-15.70-302.25]
= 75.83 KN.m

Problem 6 (3 pts) Refer to Hibbeler problem 3.20 for: Use 2.2 Mg, 1.3 Mg, 0.5 Mg, 7.9
m, 3.2 m, 7.6 m and 14.1 m instead of 2 Mg, 1.5 Mg, 0.5 Mg, 7.5 m, 4 m, 9.5 m and 12.5
