1. A 25 kg wooden plate is held in place by two strings attached to the ceiling and the wall. The string attached to the ceiling makes an angle \( 40^{\circ} \) with the horizontal and the string attached to the wall makes \( 90^{\circ} \) with the wall. Determine the force in each string.

Step 1
The weight of an object is given by the formula W = mg, where m is the mass of the object and g is the acceleration due to gravity. Here, m = 25 kg and g = 9.8 m/s^2. So, W = 25 kg * 9.8 m/s^2 = 245 N. Show more…

Algebraically. You may also choose to solve some of them graphically to check your answers. A child's swing is held up by two ropes tied to a tree branch that hangs $13.0^{\circ}$ from the vertical. If the tension in each rope is $2.28 \mathrm{N},$ what is the combined force (magnitude and direction) of the two ropes on the swing?

The horizontal, uniform, 120 - $\mathrm{N}$ board drawn in Fig. $5-19$ is supported by two ropes as shown. A $0.40-\mathrm{kN}$ weight is suspended one-quarter of the way from the left end. Find $F_{T 1}, F_{T 2}$, and the angle $\theta$ made by the rope on the left.
Find the tension forces on the strings attached to a box hanging on the ceiling at both ends, making angles of 33.2 degrees and 55.8 degrees respectively from the horizontal.
