Hello,
I'm asked to give an expression of S and F in function of theta. This is possible due to 3 given equations. If I make a matrix of these equations and use the linsolve there is an error because of the parameter thetea. Can someone help?
Kind regards,
Tuur
syms theta S Fr = 0.025;h = 0.3;rho = 7850;g = 9.81;m = r^2 * pi * h * rho;phi = atan((0.15 - 0.15*sin(theta))/(0.15*cos(theta)))F_g = [0 , -m * g];F_s = [-S*cos(phi), S*sin(phi)];F_p = [F*cos(theta), F*sin(theta)];eq1 = F_g(1) + F_s(1) + F_p(1) == 0;eq2 = F_g(2) + F_s(2) + F_p(2) == 0;eq3 = 0.15*cos(theta)*F*sin(phi) - 0.15*sin(theta)*F*cos(phi) + m * g * 0.15 * cos(theta) == 0;A = [-cos(phi), cos(theta); sin(phi), sin(theta); 0, 0.15*cos(theta)*sin(phi) - 0.15*sin(theta)*cos(phi)]B = [0; m * g ; -m * g * 0.15 * cos(theta)]
