Using mathlab:
input required

m=input('Enter Mass of the bean : ');
F1=input('Enter Triangular Distributed Load : ');
F2=input('Enter Rectangular Distributed Load : ');

g=9.91;

a)Convert the triangular distributed distance load (F1) into point load (P1y) and find its distance (d1) from pin A
P1y=1/2*x1*F1
d1=x1/3

b)Convert the rectangular distributed load (F2) into point load (P2y) and find its distance (d2) from pin A 2
P1y=1/2*x1*F1
d1=x1/3

c)Convert the rectangular distributed load (F2) into point load (P2y) and find its distance (d2) from pin A 2
P2y=x2*F2
d2=x1+(x2/2)

d)convert the angle from degree to radian
angle radains=(theta*3.14)/180

e)Resolve the point load (F3) into x-direction (P3x)
P3x=F3*sin theta

f)Resolve the point load (F3) into y- direction (P3y)
P3y=F3*cos theta

g)Find the distance (d3) between the point load (F3) and pin A
d3=(x1+x2+x3+x4)*sin theta

h)Find the horizontal reaction force at pin A (RAx)
RAx=P3x

i)Find the vertical reaction force at roller B (RBy)
RBy=(P3y*(x1+x2+x3+x4)+P2y*d2+P1y*d1)/(x1+x2+x3)
-
g)Find the vertical reaction force at pin A (RAy)
Ray=P1y+P2y-RBy+P3y

k)Find the resultant reaction force (RA)
RA=square root RAx square+RAy square
