I really need some help with this:
A mass of 15 kg is suspended by two cords from a ceiling. The cords have lengths of 15 cm and 20 cm, and the distance between the points where they are attached on the ceiling is 25 cm. Determine the tension in each of the two cords.
thanks in advance.
let A be the point where the 15 cm string is attached to the ceiling.
C be the point where the 20 cm string is attached to the ceiling.
B be the point directly above the hanging mass between A and C.
M is the mass position.
ABM and CBM are right triangles.
AC = 25 cm , AB = x cm , BC = (25-x) cm
using Pythagoras ...
... BM = 12 cm
let = tension in the 15 cm string
= tension in the 20 cm string
= acceleration due to gravity
system is in equilibrium ...
solve the system for and
