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...

Q4 http://img141.imageshack.us/my.php?image=q4wp7.jpg m = 17kg L= 6m theta = 85 degrees Calculate the force (in N) required for equilibrium.

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...

hey are u still out there radou? could u possibily help me on another couple questions? :!)

is there anybody, out there? (pink floyd)
