Homework Statement
An assembly shown in the picture, GH , HK, HNL are three cables. the mass of box L is 52Kg,
a) determine the mass of box K in order to make angle theta as 25 degrees
Homework Equations
FX=0
FY=0
The Attempt at a Solution
right i started with
Fhn x cos(25) = Fhg x cos(0) as cos(o) is 1 i then wrote it out as
Fhn x cos(25) = Fhg
box L = 52Kg, i know HN = NL does the tension force NL= 52?
i know that when i get HN by looking at the forces acting on L & using Newtons 1st law to solve for NL i can calculate Fhg from the equation i started with. confused on how to get HN=NL thinks its 52.
then at joint H, the vert comp of HN must equal the tension in HK, per Newton 1st law in the y direction, and then i look at the forces acting on K to solve for its mass. i understand the theory I'm just confused about the calculations that need to be made, can anyone run through it with me please to find the mass of box K?
