I need help solving this problem

**Title: Calculating Maximum Torque in a Dual Shaft System**

**Problem Description:**

An inner solid shaft with a diameter of 1.5 inches is connected, by a rigid plate, to an outer hollow shaft. The outer shaft has an outer diameter of 3 inches and a wall thickness of 0.125 inches. The outer shaft is then attached to a rigid ring and bolted to a supporting fixture. The inner shaft is made of 2014-T6 aluminum, and the outer shaft is made of titanium.

**Task:**

Calculate the maximum torque that may be applied to the system so that the maximum shear stress remains less than the yield strength for both shafts. To solve this, you will need to determine the allowable torque in each shaft and then use the smaller of the two for your answer.

**Diagram Explanation:**

The diagram illustrates the dual shaft system:
- The inner shaft, labeled as the "Inner Shaft," is depicted vertically with a height of 4 inches.
- It connects to the outer shaft, which surrounds it and is labeled as the "Outer Shaft." The height of the outer shaft is 8 inches.
- The outer shaft has an outer diameter measurement marked at 3 inches.
- The torque (T) is shown as being applied at the top of the inner shaft, directing vertically upwards.
