Lift cable tension: 1,000 kg accelerating down at 1.2 m/s²

Answer: tension = 8,606.65 N (tension 877.634 kgf).

What we know

  • Mass: 1000 kg
  • Acceleration (up +, down −): -1.2 m/s²

Step by step

Given
m = 1000 kg, a = -1.2 m/s²
Formula
T = m × (g + a)
Substitute
T = 1000 × (9.80665 + (-1.2))
Result
T = 8,606.65 N

All results

The physics

Tension is the pulling force transmitted along a rope, cable or string when it is stretched taut. For an ideal (massless, inextensible) rope over a frictionless support, that force is the same at every point — which is why one number describes the whole rope.
