1.Use the Frobenius method to solve: xy"-y=0 . Find index r and recurrence relation. Compute the first 5 terms (a0 - a4) using the recurrence relation for each solution and index r.
2.You will be using a large crane... lets say one with a capacity of 30T. What considerations need to be made prior to picking up a 15T load with the crane? If you are familiar with the use of a crane be sure to include the discussion of the outriggers and other safety features.
The two shafts are made of A-36 steel. Each has a diameter of 25 mm and they are connected using the gears fixed to their ends. Their other ends are attached to fixed supports at A and B.
