A uniform rod with a weight of $20\,\text{N}$ and a length of $2.0\,\text{m}$ is subjected to two vertical forces, as illustrated. The forces indicated are $15\,\text{N}$ and $5.0\,\text{N}$. What are the resultant force acting on the rod and the resultant moment about the centre of gravity of the rod?
- Aresultant force $=0\,\text{N}$, resultant moment $=10\,\text{N m}$
- Bresultant force $=0\,\text{N}$, resultant moment $=20\,\text{N m}$
- Cresultant force $=20\,\text{N}$, resultant moment $=10\,\text{N m}$
- Dresultant force $=20\,\text{N}$, resultant moment $=20\,\text{N m}$
