The maximum stress in a section of a circular tube subject to a torque is τmax = 27 MPa . If the inner diameter is Di = 3.75 cm

DIA [1.3K]

Answer:

$T_{max} = 4.735\,kN\cdot m$

Explanation:

The shear stress due to torque can be calculed by using the following model:

$\tau_{max} = \frac{T_{max}\cdot r_{ext}}{J_{tube}}$

The maximum torque on the section is:

$T_{max} = \frac{\tau_{max}\cdot J_{tube}}{r_{ext}}$

The Torsion Constant for the circular tube is:

$J_{tube} = \frac{\pi}{32}\cdot (D_{ext}^{4}-D_{int}^{4})$

$J_{tube} = \frac{\pi}{4}\cdot [(0.053\,m)^{4}-(0.038\,m)^{4}]$

$J_{tube} = 4.560\times 10^{-6}\,m^{4}$

Now, the require output is computed:

$T_{max} = \frac{(27\times 10^{3}\,kPa)\cdot (4.560\times 10^{-6}\,m^{4})}{0.026\,m}$

$T_{max} = 4.735\,kN\cdot m$

Write a function to accept a vector of masses (m) from the user and gives the corresponding energy to them. Energy vector is the

jarptica [38.1K]

Answer:

Written in Python

def energyvector(mass):

c = 2.9979 * 10**8

energy = mass * c ** 2

print(round(energy,2))

Explanation:

This line defines the function

def energyvector(mass):

This line initializes the speed of light

c = 2.9979 * 10**8

This line calculates the corresponding energy

energy = mass * c ** 2

This line prints the calculated energy

print(round(energy,2))
