Expert Solution

Step 1

Here, co-ordinates of points are,

A(0,0,-1), B(1cos135⁰,-1cos135⁰,0)=B(-0.707,0.707,0) ,C(1,0,0),D(0,-1,0)

So, now Force along chain is given by force value multiply by unit vector in that direction as

$F_{A B} = F_{A B} (\frac{- 0.707 \hat{i} + 0.707 \hat{j} + 1 \hat{k}}{\sqrt{{(- 0.707)}^{2} + 0 . 707^{2} + 1^{2}}}) = - 0.5 F_{A B} \hat{i} + 0.5 F_{A B} \hat{j} + 0.707 F_{A B} \hat{k} F_{A C} = F_{A C} (\frac{1 \hat{i} + 1 \hat{k}}{\sqrt{1^{2} + 1^{2}}}) = 0.707 F_{A C} \hat{i} + 0.707 F_{A C} \hat{k} F_{A D} = F_{A D} (\frac{- 1 \hat{j} + 1 \hat{k}}{\sqrt{{(- 1)}^{2} + 1^{2}}}) = - 0.707 F_{A D} \hat{j} + 0.707 F_{A D} \hat{k}$

$F = - 800 \hat{k}$
