Homework Statement
Two objects of equal mass m are whirling around a shaft with a constant angular velocity ω. The first object is a distance d from the central axis, and the second object is a distance 2d from the axis. You may assume the strings are massless and inextensible. You may ignore the effect of gravity. Find the tensions in the two strings.
Homework Equations
F(net) = ma
α = ω^2*r
a = αr
The Attempt at a Solution
First string:
If gravity is ignored, the only force acting on the object is tension. Thus,
T = ma
and
T = m(ω^2*d^2)
Second string:
T = ma
and
T = m(ω^2*(2d)^2)
T = m(ω^2*4d^2)
Are there any other forces acting on the objects?
