Question

3. During design and build of any engineering system, it is vital to subject it to extensive testing. Accordingly, one such mechanical system has been subjected to similar tests. In the process, you are required to create a set of 10 random samples for each of the four pressure systems. Create a random matrix of size 10x4 using MATLAB functions such as: for loops and rand. 4. A 3000 pound vehicle is traveling on a road at 100 ft/sec requires a force of F = ma (m=3000) to stop, where 2 Vo = 100,vi = 0 Write a MATLAB program to calculate the retarding force needed to stop the car at distances, d=20, 30, 40, 50,...,100 ft. Output the values of d and F.

A=[];

for i=1:10

for j=1:4

A(i,j)=rand()*5;

end

end
