The overhanging beam shown is supported by a roller and pinned support as shown. The applied moment at $B$ is removed and replaced by a couple consisting of forces applied at points $A$ and $C$. 11) What is the magnitude of the couple that exactly replaces the applied moment that is removed? a. $0.08\mathrm{N}?\mathrm{m}$ b. $0.16\mathrm{N}?\mathrm{m}$ c. $2.5\mathrm{N}?\mathrm{m}$ d. $15\mathrm{N}?\mathrm{m}$ 12) What is the magnitude of the forces that constitute the applied moment? a. $2.1\mathrm{N}$ b. $4.2\mathrm{N}$ c. $6.3\mathrm{N}$ d. $8.3\mathrm{N}$ 13) If you replace the $100\mathrm{N}/\mathrm{m}$ distributed load with an equivalent resultant force, what is its magnitude and where does it act relative to $A$. a. $100\mathrm{N},0.4\mathrm{m}$ b. $40\mathrm{N},0.2\mathrm{m}$ c. $100\mathrm{N},1.0\mathrm{m}$ d. $40\mathrm{N},1.0\mathrm{m}$
