A disabled automobile is pulled by means of two ropes as shown. The tension in rope AB is 2.2 kN. and the angle alpha is 25 degree. Knowing that the resultant of the two forces applied at A is directed along the axis of the automobile, determine by trigonometry (a) the tension in rope AC, (b) the magnitude of the resultant of the two forces applied at A.

Step: 2

Apply sine rule.

Here, R is the resultant and is the tension in rope AC.
Calculate the tension in rope AC using the equation.

Therefore, the tension in rope AC is.
