Problem
A solid uniform ball with mass m and diameter d is supported against a vertical frictionless wall by a thin massless wire of
length L. a) Find the tension in the wire.
m
Solution
a)
Let us first derive the expression for the tension.
By Newton's First Law
ΣΕ -
the components of force that makes this so is
ΣF T
= 0
Simplifying this results to
T =
g/
(4)
Analyzing the figure above, we arrive at
(0) = sqrt(
2.
By substitution, we arrive at the following:
T =
+2
)g/(
2.
sqrt (
If the ball has a mass of 45 kg and diameter 32 cm, while the wire has a length of 30 cm. The tension is equal to
0.370 N
