I am trying to calculate the pressure required for a specific bend angle produced by my actuator
But when evaluating the triple integral for calculating the moment the error of too many level recursions is recieved
Any help or advice is appreciated

Code:
a = 0.11e-1;

b = 0.25e-2;

t = 0.25e-2;

theeta = (1/180)*pi;

L = 0.17e-1;

R = L/theeta;

shearmodulus = 314000;

0.011 = 0.011 0.0025 = 0.0025 0.0025 = 0.0025 1 1 --- Pi = --- pi 180 180 0.017 = 0.017 R = 0.9740282516 314000 = 314000 eq0 := Ma = int(int((x*sin(O)+b)*x^2*(cos(O)*cos(O)), O = 0 .. (1/2)*Pi), x = 0.9e-2 .. 0.11e-1); -9 eq0 := Ma = 1.067341412 10 assign(('t', 'b', 'L', 'shearmodulus', 'theeta', 'a') = (0.25e-2, 0.25e-2, 0.17e-1, 314000, (1/180)*Pi, 0.11e-1));

eq4 := Mo1 = int(int(2*shearmodulus*(1+Beeta*theeta/L-1/(1+Beeta*theeta/L)^3)*(O+t)*L, O = 0.9e-2 .. 0.11e-1), Beeta = 0 .. b);

eq4 := Mo1 = 0.000003416445428 simplify(Mo1 = int(int(2*shearmodulus*(1+Beeta*theeta/L-1/(1+Beeta*theeta/L)^3)*(O+t)*L, O = 0.9e-2 .. 0.11e-1), Beeta = 0 .. b)); Mo1 = 0.000003416445428 simplify(Mo1 = int(int(2*shearmodulus*(1+Beeta*theeta/L-1/(1+Beeta*theeta/L)^3)*(O+t)*L, O = 0.9e-2 .. 0.11e-1), Beeta = 0 .. b));

Mo1 = 0.000003416445428 Mo2 = 2*(int(int(int(shearmodulus*((R+b+sin(Phi)*(A+tao))/R-1/((R+b+sin(Phi)*(A+tao))/R)^3)*((A+tao)^2*sin(Phi)+b*(A+tao))*L, Phi = 0 .. (1/2)*Pi), A = 0.9e-2 .. 0.11e-1), tao = 0 .. t));

Error, (in depends) too many levels of recursion eq5 := Pressure = Mo/Ma; Mo eq5 := Pressure = -- Ma
