1.A belt is wrapped around a pulley for 180 degrees. The loose-side belt tension is 100 lb and the coefficient of static friction is 0.30. Calculate the maximum belt tension if motion is impending. Assume

A) a flat belt and

B) a V-belt with a groobe angle of 50 degrees

2.Write an M-file to calculate the factorial function of N!, as defined by: N!=1 N=0 N!=N*(N-1)*(N-2)*...*3*2*1 N>0 The MATLAB code to calculate N factorial for positive value of N would be n_factorial=1 for 11=1:n n_factorial=n_factorial*ii; end Be sure to handle the special case of 0! Alos, be sure to report and error if N is negative or not and integer

3.Examine the following for statements and determine how many times each loop will be executed.

a) for ii= -32768:32767

b) for ii= 32768:327667

c) for kk= 2:4:3

d) for jj= ones (5,5)

4.Write the matlab statements required to calculate and print out the squares of al the even integers between 0 and 50. create a table consisting of each integer and its square, with appropriate labels over each colum.
