Question:
A 70 lb bag of rice is being pulled by a person by applying force F at an angle q as shown.
The force required to drag the bag is given by:
Where ? = 0.35 is the friction coefficient.
(a) Determine F (q) for q = 5 o , 10 o , 15 o , 20 o , 25 o , 30 o , 35 o ,
(b) Determine the angle q where F is minimum. Do it by creating a vector q it by creating a vector q with elements ranging from 5 o to 35 o and spacing of 0.01. Calculate F for each value of q and then find the maximum F and associated q with MATLAB?s built-in function max.
