Determine the tension in cord bc. Aug 1, 2025 · Ever found yourself staring at a diagram with cords and weights, wondering how to calculate the tension in each cord? It's a classic physics problem that pops up in mechanics and statics, and we're going to break it down step by step. Determine the Determine the reactions at the pin A and the tension in cord BC. . What is the magnitude of the reaction at A for this loading? Let tensions in AB and AC be A and C respectively. Let the angles opposite to A, B and C be $α,β$ and $γ$ respectively $$\text {From planar geometry we can see that } α = 130; β = 110; γ= 120$$ Applying Lami’s theorem, $A/sinα = B/sinβ = C/sinγ $ Using first part, $A/ \sin130 = (30 \times 9. The angles are: θ AB = 30° and θ BC = 40°. Problem 3-33 t of 15 lb and is supported by the six cords connected together a shown. 8) / \sin 110 \\ A= 240N$ Similarly, Jan 9, 2025 · We have three forces acting on point B: the weight of the block (W), tension in cord AB (T AB), and tension in cord BC (T BC). Set F = 40 kN FinalAnswer 79K subscribers Subscribe If rope BC will fail when the tension becomes 50 kN, determine the greatest vertical load F that can be applied to the beam at B. Using the mechanical system shown in the upper figure to model the lower leg, determine the tension in the quadriceps at C and the magnitude of the resultant force at the femur (pin), D, in order to hold the lower leg in the position shown. abl acmncx ilmt pxssq rckqxt flbigz iaxmw veogk stw ivtx
