Is there any difference?
I guess i should say why I'm interested in this question. I've often had what is called 'lucid dreams' in which i realize I'm dreaming while I'm dreaming... it doesn't happen often, but I've defeinetely experienced it. For example, in the middle of a dream, i'll...
hey,
i'm doing a course on materials science as part of an aerospace engineering degree. I'm just trying to gain a full understanding of some of the fundamental concepts involved. Would i be right in saying that, all processes that occur in metallurgy on an atomic scale (like...
for Q5 i got that that the reaction moment at A is 2.6133333 kNm.
for Q6 i got that Cv = 75kN.
for Q7 i got that the internal bending moment at B is equal to -860kNm.
for Q8 i got that the vertical reaction force at A is 9.357kN.
Q9 and Q10 are different from Q5 so I am not sure how to solve...
ok what I am going to do is quickly try to work them all out, and post my results in one reply... and if u could maybe just check that i have them right that would be so cool. ty
q10 (last question!)
http://img217.imageshack.us/my.php?image=q10mg1.jpg
a=2m
F=11kN
M=8kNm
q=4kN/m
Calculate the shear force in C (in kN_ with correct sign of deformation. Adopt the sign convention from the figure .
q9
http://img384.imageshack.us/my.php?image=q9iw9.jpg
a = 0.800m
F=20kN
M=14kNm
q=3kN/m
Calculate the normal force in C (in kN). Use correct signs for tension and compression.
q8
http://img172.imageshack.us/my.php?image=q8qp8.jpg
F = 25kn
q = 30kN
a = 5m
calculate the reaction force at A in kn, upwards positive.
PS. if u won't give me the answers then could u possibily make sure i have the right answers if i post what i think is right at the end of this...
q7
http://img88.imageshack.us/my.php?image=q7ath5.jpg
F = 20kN
q= 25 kN
a= 7m
Calculate the internal moment at B (in kNm) use the sign convention in the figure (which is U = positive)
q6
http://img138.imageshack.us/my.php?image=q5ayq9.jpg
a = 2m
F = 25kN
q = 50kN/m
Calculate the vertical reaction force in support C in kN (upwards positive)
ok here is Q5:
http://img138.imageshack.us/my.php?image=q5ayq9.jpg
q = 2kN/m
a= 0.350
Calculate the moment reaction in A (in kNm) counter clock-wise positive.
PS i really didn't mange to work out the 1st one either... please please please! do it for me, the thing is... if i don't...
ok this is actually Q11
http://img120.imageshack.us/my.php?image=qmc9.jpg
a= 0.200m
b=2m
theta= 35 degrees
Determind the torque M (in kNm) on the activating lever of the dump truck necessary to balance the load at the given dump angle theta, g = 9.81m/s2.
thankyou! btw, i know this will sound rude as some1 can sound... but i have 8 more Q's and if i don't get them all right i really am going to fail this course :( could i maybe just have the answers? believe me when i say that, i will learn the theory behind all of this stuff but i reallly am in...
