1. The problem statement, all variables and given/known data

A flagpole of mass 25kg and 2.5m in length is held in a horizontal position by a cable shown in the diagram.

The centre of gravity of the flagpole is at a distance of 1.5m from the fixed end. Determine:

a the tension T in the cable;

b the vertical component of the force at the fixed end of the pole.

2. Relevant equations

Moment=F*perp distance

vertical component=Fsin(theta)

Horizontal component=Fcos(theta)

clockwise=anticlockwise

3. The attempt at a solution

I did (a) and I got around 300.Please call out on me if i get this wrong.

Calculate the moments around the end of the flagpole(left hand)

clockwise moment=250*1.5=375

anti clockwise moment=T*1.25

through division etc, i get 300.

What i cannot understand is (b) What does it mean by the vertical component at the end of the flagpole?
