## Review Problem 4.5

Replace the force and couple system by an equivalent force and couple moment at point \( P \). Take \( F_1 = 7 \, \text{kN} \) and \( F_2 = 4 \, \text{kN} \). ([Figure 1](#)).

### Figure

A diagram shows a system involving forces and a couple moment. The \( x \) and \( y \) axes are labeled, with point \( O \) on the \( y \)-axis and point \( P \) on the \( x \)-axis. The couple moment of \( 8 \, \text{kN} \cdot \text{m} \) acts clockwise around point \( O \). 

- Force \( F_1 \) is \( 7 \, \text{kN} \) at an angle to the horizontal, originating from a point \( A \) which is \( 5 \, \text{m} \) below the \( x \)-axis. \( F_1 \) forms a right triangle with \( \frac{13}{5} \) for its adjacent side ratio.
- Force \( F_2 \) is \( 4 \, \text{kN} \) acting at a \( 60^\circ \) angle below the horizontal, \( 3 \, \text{m} \) right of point \( O \).

### Part A

**Determine the magnitude of the resultant force.**

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

\[ F_R = \underline{\qquad\quad} \]

Submit your calculated value using the input box. 

### Part B

**Determine the angle between the resultant force and the \( x \)-axis.**

Express your answer to three significant figures.

\[ \theta = \underline{\qquad\quad} \, ^\circ \]

Counted counterclockwise from the positive \( x \)-axis.

Submit your calculated angle using the input box.
