"A guitar string is set into vibration with a frequency of 512 Hz. How many oscillations does it undergo each minute?"

yanalaym [24]

Answer:

 30720 oscillation.

Explanation:

Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.

From the question,

The frequency of the string set is 512 Hz,

These means that the spring set complete 512 oscillation in one seconds

I.e

if its completes in one seconds 512 oscillation.

Then, in one minutes, it will complete x oscillation.

x = 512×1min/1seconds

But 1 minutes = 60 seconds

x = 512×60/1

x = 30720 oscillation.

A 2.5-m-long tension member (E = 70 GPa) has cross-sectional dimensions of 25 mm x 35 mm. Determine the maximum load P that may

Alja [10]

Answer:

Force = 7.3 kN

Explanation:

Elastic Modulus = Stress / Strain

Since the maximum stress applied can be 90 MPa, lets check the corresponding maximum strain using the above equation.

70 * 10^9 = 90 * 10^6 / Strain

Strain = 0.0012857

Strain = Change in length/total length

Change in Length = 0.0012857 * 2.5

Change in Length = 0.003214 m

Converted to mm this is: 0.003214 * 1000 = 3.214 mm

Thus we can see that strain is the limiting factor, and not stress. This is because with the maximum stress possible applied, we go over the strain limit.

Doing another quick calculation, we can take out the maximum stress with strain equal to 3mm/2.5m

Strain = (3/1000)/2.5

Strain = 0.0012

Modulus of elasticity = Stress/ Strain

Stress = 70 * 10^9 * 0.0012

Stress = 84 MPa

This stress is under both the strain and stress limit.

Taking out the force due to this stress:

Stress = force / area

Force = 84 * 10^6 * Area

Force = 84 * 10^6 * (25/1000) * (35/1000)

Force = 7350 N or 7.3 kN
