The 1360-kg car and the 2100-kg tow truck are stationary. The muddy surface on which the car s tires rest exerts negligible friction forces on them. What is the tension in the tow cable

Respuesta :

Answer:

5.91 kN

Explanation:

The schematic view of the free body diagram of the car is shown in the image attached below.

Let's first calculate the weight of the car.

W = mg

W = 1360 × 9.81

W = 13341.6 N

W = 13.3416 kN

From the image, Using the equilibrium equations, we have:

[tex]\sum F_x = 0\\[/tex]

T cos (18° - 10°) - 13.3416 sin 26° = 0

T cos 8° - 5.84857 = 0

T cos 8° = 5.84857

[tex]T = \dfrac{5.84857}{cos \ 8^0}[/tex]

[tex]T = \dfrac{5.84857}{0.9903}[/tex]

T = 5.905856811 N

T ≅ 5.91 kN
