From the following diagram, determine the effort applied. (The bar is of negligible mass)

From the following diagram, determine the effort applied. (The bar is of negligible mass).

---

Taking moments about O. Then, clockwise moments = effort × 200 cm.
Anticlockwise moments = 200 × 30 cm.
Effort = (200 × 30)/ 200 = 30 N.
