- 1) The non-elongated length of the spring AB is 8 m. If the block is held in the equilibrium position equilibrium position shown, determine the mass of the block at D.

2) Replace the system acting on the frame by an equivalent resultant force and specify the point, measured from B, where the line of action of the resultant intersects element BC.

- Relevant Equations
- 1) Σfx=0, Σfy=0 and F=kx

2) Σfx=0, Σfy=0, Θ=arctan(Σfy/Σfx) and ΣMb=Mrb
