线性方程组的一样解法,消元
T1=1/4*G*(a*sin(theta)-20)*cos(theta)/(-10*cos(theta)*sin(theta)-7+7*cos(theta)^2)
T2=-1/28*G*(28-28*cos(theta)^2-2*a+2*cos(theta)^2*a+40*sin(theta)+cos(theta)*a*sin(theta)-20*cos(theta))*cos(theta)/(-1+cos(theta)^2)
T3=-1/14*cos(theta)*G*(-7*a*sin(theta)+2*cos(theta)^2*a*sin(theta)-10*a*cos(theta)+10*a*cos(theta)^3+140-40*cos(theta)^2+200*cos(theta)*sin(theta))/(10*cos(theta)*sin(theta)-10*cos(theta)^3*sin(theta)+7-14*cos(theta)^2+7*cos(theta)^4)
