A uniformed lath AB of length 80 cm and mass of 50g is pivoted at a point p,25 cm from one end it is kept horizontal by support at the other end by a vertical string. Calculate the tension in the string.

I am asking and I know I can't but I don't no the answer to the question. So please answer.
I don't know what a lath is. But this is a torque question. Sum the torques around the end: Fn(.25) - mg(.40) +T(.80) = 0. Then sum the forces as well. Two eq, two unknowns (Fn and T).
