Answer:
Tension T = 17 N
Explanation:
Given:
Mass of the beam M = 3.00 kg
Length of the beam L = 2.00 m
Angle θ = 60.0°
Solution :
The beam is fixed on the wall by the hinge. Since the beam is uniform, the center of mass will be at its geometric center
Since it is at equilibrium, the net torque mus be zero. The weight of the beam is pulling it down and the vertical component of the tension is lifting it up.
The period of any wave is the time it takes for its angle
to go from zero to 2pi .
The 'sin' function is a wave. The angle of this one is (8pi t).
When t=0, the angle is zero.
Wonderful.
Now, how long does it take for the angle to grow to 2pi ?
I*n other words, when is (8pi t) = 2pi ?
Divide each side by '2pi': . . . . . 4 t = 1
Divide each side by ' 4 ': . . . . . t = 1/4
And there you are. Every time 't' grows by 1/4, (8pi t) grows by 2pi.
So if you graph this simple harmonic motion described by 'd', you'll
see the graph wiggle up and down with a period of 1/4 .
Answer:
A conversion factor is an expression for the relationship between units that is used to change the units of a measured quantity without changing the value. A conversion ratio (or unit factor) always equals one (1), where the numerator and the denominator have the same value expressed in different units.
