but unfortunately i havent had much experience with moments

find the normal forces applied to the installed stud at points A and B

l-----360mm--l--85-l

A.====

P.=========== /==/

====.B

length from P to A = 360MM

length of A to B = 85mm

thickness of timber between A and B is 45mm (or vertical distance between A and B)

for applied at point P is 150N

ignore friction

so far i understand that the force applied to the centre of the stud

is 360/1000 * 150N = 54NM

then you have a couple of 85/1000 * 150N = 12.75nm

is this the correct way of attempting this question

if so how does the couple and the for applied to the lever interact to give me the force on points A and B of the stud?
