Q2_1_2 Answers
1) (TCX+2Lt0)/(G0I) where TCx=-t0L/3
2) t0(3L-x))/(2G0I)
3) x=3L
Q2_1_1 Answer
TCx=-t0L/3
I need to know if this information is correct, because I solved the problems without correspondent images
Let me know if solutions are correct to go with the next problems.
I put this Q2_1_1 Answer but the answer its wrong i put this -t_0*(L/3) and the answer is wrong
Q2_1_2 Answers
1) (TCX+2Lt0)/(G_0I) where TCx=-t_0L/3
and I=pi*R^4/2 so answer:
(2*TCX+4*L*t_0)/(G_0*pi*R^4)
2) t0(3L-x))/(2G0I)
where I=i*R^4/2 so
answer: ((t_0*(3L-x))/(pi*R^4)
3) x=3L
Where I can see images of the problems ?

OK Let me see Answer Q2_1_1:
Sum=0
-Tx_1+INTEGRAL{3L-L}t_0*dx+TXC=0
so Tx_1=2*L*t_0+TXC {0<=x<=L}
-Tx_2+INTEFRAL{3L-x}t_0*dx+TXC=0
so Tx_2=t_0*(3L-x)+TXC {L<=x<=3L}
d*phi/dx =Tx/GI
so in x<=_x<=L
d*phi/dx= (TXC+2*L*t_0)/G_0*I
in L<=x<=3L
d*phi/dx= (t_0*(3L-x)+TXC)/(2G_0*I)
in x=3l Phi=0
so
0=INTEGRAL{0,L}(TXC+2*L*t_0)/G_0*I+INTEGRAL{L,3L}(t_0*(3L-x)+TXC)/(2G_0*I)
0=(3*L*TXC+3*L^2*t_0)/(g_0*I)
TXC=-L*t_0
Ok, I believe that this is the correct answer for Q2_1_1
Solving for TXC
TXC=
