Question

solve this using matlab please

Task 3: [25 marks] Consider the force applied at the end of the lever. If you apply a force to the lever close to the pivot point, the effect is different than if you apply the force further out on the lever. That effect is called Moment given by the formula; M = r *F Here r and F are the position vector and the force vector respectively. ř = ai + bj +ck F = li+mi+nk Write the function to calculate M, using the vectors r and F. b) Write an M-file program which calculates MomentM, about the pivot point on the lever for a force F = -100 + 20j + ok with the assumption of lever length 12 inch, at an angle of 45 degrees from the horizontal. Gives the position vector as 7 = 12 i + 123 + OK V250 C) Write a general M-file for the calculation of Moment which prompts the user for the x,y anz z components of the position and the force vectors.

Fx=input('Enter x component for force: ');
Fy=input('Enter y component for force: ');
Fz=input('Enter z component for force: ');
rx=input('Enter x component for position: ');
ry=input('Enter y component for position: ');
rz=input('Enter z component for position: ');
F=[Fx,Fy,Fz];
r=[rx,ry,rz];
M0=norm(calculateMoment(r,F))

function M=calculateMoment(r,F)
M=cross(r,F);
end

Kindly revert for any queries

Thanks.
