hi please help me with my assignement.

this beam made of steel with moduus youg of 300 gpa, cross sectional area A1 =10.10^-6 m2
A2 = 20. 10^-6 m2.
length L1 = 2m
Length L2 =1,8 m.

at he level that is very rigid ring mounted to apply the load F=8 KN.

Tension and stress of a chain lifting a beam

Submitted by John Galang Peña on June 28, 2015 - 10:45pm

The 5m uniform steel beam has a mass of 600 kg and is to be lifted from the ring at B with the two chains, AB of length 3m., and CB of length 4m. a.)Determine the tension T in chain AB when the beam is clear of the platform. b.) stress if the cross-sectional area is limited to 500 mm2.

1. eliminate the arbituary constant on this eqn. y=C1e^2x+C2e^x+C3

2. evaluate and find the general solution of this eqn.
a. x sqrt1+y^2 dx - y sqrt1+x^2 dy=0
b. 2ycosxdx+3sinxdy = 0

thank you so much. god bless! ^_^
