Here, d in the moan diameter of the screw thread, f is the coeficient of friction, and I is the lead of the
screw. The lend can be calculated from
where n is the number of starts on a thread.
If the outside diameter, d, and pitch, p. is known, the mean dianeter can be calculated from:

Write a matlab function called hut p3_lastnae that accepts as imputs
• outside diameter (mm)
• pitch (mm

and returns the torque as the output. Your code shoukd ako priut a line to the ocommand window
formatted as follows
Torque - xK.XI Ne
Here the torque should be giveu to 2 decimal places and have the mits print afterward.

Homework #6
MET321 Analytical Tech.
Due: Thursday, A pril 12
Problem 1
Rotational speed can be measured in revolutions per minute (rpm) or in radinn per second (rad/s). Write a
MATLAB function caled hu4_pl_lastnane that accepts as imput rotational speed in rpm and provides as
output the rotational spoed in rad/s. For example if the input is 60 rpm, the output should be 6.283185
rad/. The function should also print a line on the screen that says:
Rotational Speed: 60 rpa - 6.238 rad/a
Notice the rad/s value is limited to 3 decimal places.
Problem 2
In a separate script file called hu4 lastname, u your function from problem I to convert the following
values to rad/
. 60 rpm
• 1000 rpm
• 5200 rpa
