Alloys

An alloy is an admixture of two or more metals or a metal and a non-metal. Since ancient times, man has been using alloys. Alloying helps to retain the properties of the parent matter, such as hardness, strength, toughness, ductility and is corrosion-resistant. Copper alloys such as brass have antimicrobial properties that help to fight against (Coronavirus disease 2019) COVID-19 and other hospital-acquired infections. Some common alloys are brass, bronze, solder steel, etc. Most alloys have a lower melting point than their constituents. This is due to the presence of a nonmetal as one of the constituents that behaves as an impurity and restricts the raise of melting point.

Question

**Part D - Analyzing a system of forces acting on a concrete slab**

The concrete slab shown in the picture is subject to four forces, \( F_1 = 220 \, \text{lb}, \, F_2 = 320 \, \text{lb}, \, F_3 = 635 \, \text{lb}, \) and \( F_4 = 225 \, \text{lb}. \)

**Figure 3**

The dimensions are \( d_1 = 7.0 \, \text{ft}, \, d_2 = 26 \, \text{ft}, \, d_3 = 5.0 \, \text{ft}, \, d_4 = 16 \, \text{ft}, \) and \( d_5 = 8.5 \, \text{ft}. \)

Determine the equivalent resultant force by specifying its magnitude and its location \((x, y) \) on the slab.

**Express your answers, separated by commas, to three significant figures.**

[View Available Hint(s)]

- Input fields are available for entering the results for \( F_R, x, \) and \( y \) in the format: "__ lb, ft, ft".

There are no graphs or diagrams to explain further.

**Learning Goal:**

To replace force-couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be applied.

Certain force-couple systems can be replaced by a single force. The requirement is that the lines of action of the resultant force, \( \mathbf{F}_R \), and the resultant couple moment, \( (M_R)_O \), are perpendicular to each other. This is equivalent to saying the following types of force systems can be simplified to a single force.

- **Concurrent force system:** This is a system where all the lines of action of the applied forces intersect at a common point. Because this means all the

**Figure Explanation:**

The diagram shows a rectangular plate with four forces (\( F_1, F_2, F_3, F_4 \)) acting downward at different positions on the plate. Each force is represented by a blue block with an arrow pointing downward, suggesting the direction of the force.

- \( F_1 \) is applied at the far right corner of the rectangle along the y-axis.
- \( F_2 \) is located to the left of \( F_1 \) but still along the y-axis.
- \( F_3 \) is directly opposite \( F_4 \) along the x-axis.
- \( F_4 \) is at the left corner on the x-axis.

The distances between the points where the forces are applied and the axes are denoted by \( d_1, d_2, d_3, d_4, \) and \( d_5 \).

This figure represents a 3D view of how the forces are applied to the structure.
