Question

The diagram shows two forces Fi =5N and Fii=3N acting at points A and B of a rod pivoted at a point O ,such that OA =2 m and OB= 4m. Find (1) the moment of force Fi about O (2)the moment of force Fii about O(3) total moment of two forces about O

Answer 1

Answer:

(1)moment at o due to Fi=5*2-10 Nm

(2)moment at o due to Fii=3*4=12Nm

(3)need diagram
