Question
a uniform rod is 1m caring a weight of 100N calculate its tension of the string holding it an the reaction at the hinge

I assume it is sticking out horizontal from wall.
I assume the weight is in the middle
I assume the string is vertical, if not divide T by cos angle where angle is angle of string from vertical.
moments about hinge
100 (1/2) -T (1) = 0
T = 50 N
then you also need 50 N up at hinge
force back on wall at hinge = T/sin angle
