Question

6.14 Consider the hoist described in Problem 5.16, where a 500-N weight is being lifted by a rope wound around the cylinder, with an unknown friction coefficient, Mu. An engineer has measured the tension T2 required to support the 500-N load to be 950 N at a contact angle of theta = 85degree. Determine the friction coefficient Mu by: a. Putting the equation for rope tension in standard form. b. Plotting the equation using MATLAB. c. Using the MATLAB fzero command to find the appropriate solution for contact angle theta. d. Checking your answer by re-solving it using the Excel Goal Seek tool.

Explanation / Answer

>> w=950;

>> theta=85;

>> u=w*sin(theta)

u =>> x = fzero(@sin,85)

x =
