Analyze balanced cable geometry with flexible inputs. Switch units, inspect components, and compare operating margins. See results, exports, and graphs directly above the form.
This calculator uses a balanced two-cable support model with equal cable angles and equal cable tensions.
This page assumes a balanced load carried by two identical cables at the same angle.
W = 2T sin(θ)T = W / (2 sin(θ))θ = sin⁻¹(W / 2T)V = T sin(θ) for the vertical component of one cable.H = T cos(θ) for the horizontal component of one cable.W = mg when load is entered as mass.Here, W is load force, T is tension in one cable, and θ is the cable angle measured from the horizontal.
| Case | Load Force (N) | Angle from Horizontal (°) | Tension per Cable (N) | Vertical Component per Cable (N) | Horizontal Component per Cable (N) |
|---|---|---|---|---|---|
| Example 1 | 100.00 | 30.00 | 100.00 | 50.00 | 86.60 |
| Example 2 | 250.00 | 45.00 | 176.78 | 125.00 | 125.00 |
| Example 3 | 500.00 | 60.00 | 288.68 | 250.00 | 144.34 |
| Example 4 | 980.00 | 75.00 | 507.28 | 490.00 | 131.28 |
It assumes two identical cables support one load symmetrically. Both cables share the same angle and the same tension. That makes the standard equilibrium equation simple and reliable for balanced hanging systems.
You can use either reference. The calculator lets you choose the entered angle basis, then converts it internally. It also reports both angle forms in the results for quick checking.
Yes. Choose the mass option and enter kg, g, or lb. The page converts mass into weight force using the gravity value you provide, then performs the tension-angle calculation.
At small angles, each cable contributes only a small vertical component. The system then needs much larger cable tension to support the same load, which is why shallow cable arrangements can be risky.
No. This version is for balanced two-cable geometry only. If the cables have different angles or different tensions, you need a full static equilibrium model with separate horizontal and vertical equations.
Force inputs support N, kN, and lbf. Mass inputs support kg, g, and lb. The page also converts results into selected display units, helping with both metric and imperial workflows.
No. The calculator focuses on static force balance. It does not model elastic stretch, dynamic motion, sag, shock loading, material nonlinearity, or connection behavior. Use engineering design checks for those effects.
Use it for estimation, planning, and quick verification. Final lifting, rigging, or structural work should be reviewed against applicable codes, hardware ratings, safety factors, and a qualified engineer’s judgment.
