Question
Just need help and explanation on this question, wasn't discussed in class. Thanks!
![4. A 20 kg object is suspended by two cables as shown in figure below. The tensions T1 and T2 satisfy the following
system of equations
0.5T1 = 0.866T2
(1)
0.5T2 + 0.866T1 = 196
(2)
(a) Write the system of equations (1) and (2) in the matrix form AT = b, where T =|A In other words, find
matrices A and b. What are the dimensions of A and b?
(b) Find Ti and T2 using the matrix algebra method. Perform all matrix computation by hand.
(c) Find Ti and T2 using Cramer's rule.
