If the cable CB is horizontal and the beam is at rest in the position shown, determine the tension in the cable at the instant the towing force F = 1500 N is applied. The coefficient of friction between the beam and the floor at A is
A = 0.3. For the calculation, assume that the beam is a uniform slender rod having a mass of 100 kg.
| A. | TCB = 636 N |
| B. | TCB = 1206 N |
| C. | TCB = 1016 N |
| D. | TCB = 347 N |
