Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Question

**Problem Statement: Stress Analysis of a Jammed Drill**

The drill is jammed in the wall and is subjected to the torque and force shown.

**Diagram Explanation:**

- The diagram depicts a hand-held drill that is jammed against a wall. The drill is oriented such that torque and force are applied.
- A torque of \(20 \, \text{N} \cdot \text{m}\) is applied about the drill's axis.
- There is a force of \(150 \, \text{N}\) acting at an angle, presumably relative to the horizontal axis.
- The drill bit penetrates the wall at section \(a-a\), 125 mm from the wall surface.
- Other dimensions include:
- The drill's length from the handle to the end of the bit is 400 mm.
- Section \(A\) is 5 mm along the drill bit from the edge of the wall.

**Objective:**

**Part A:**

Determine the normal stress (\(\sigma_A\)) at point \(A\) on the cross-section of the drill bit at section \(a-a\).

- Express the answer to three significant figures with appropriate units.
- Enter a negative value for compression and a positive value for tension.

**Answer:**

\(\sigma_A = \, \_\_\_\)

**Part B:**

Determine the transverse stress \(((\tau_{xy})_V)_A\) at point \(A\) on the cross-section of the drill bit at section \(a-a\).

- Express the answer to three significant figures and include the appropriate units.

**Answer:**

\(((\tau_{xy})_V)_A = \, \_\_\_\)
