Correct Answer: 0.002021
Topic: Torsion
The shaft is attached to rigid fixed supports at each end. The maximum shear stress will be
equal in both segments when the torque T is applied at B Determine the dAB.
Use 2 decimal
places.
Use the given sign convention for uniformity.
Problem 4:
Values:
a = 300 mm
b = 75 mm
c = 100 mm
Use the graphical method to break F into components
parallel to bars AB and BC. If the component parallel to
bar AB is 7 kN, what is the magnitude of F?
Comments:
B
This is a perfect example of why the graphical method is useful - we are asked to resolve a force
into components that are not perpendicular to one another. It's difficult to apply regular old sine
and cosine (i.e. trig) for this because we're not dealing with right triangles. Instead we will use
the law of sines and/or the law of cosines.
• Start by drawing a vertical line to represent the vector F.
Now draw a line parallel to AB passing through the top of F, and another line, also parallel to AB,
through the bottom.
Repeat for BC.
You should have a parallelogram divided into two triangles by the resultant vector F. Pick one of
the triangles to work with, use geometry to figure out the angles, and then apply the law of sines
to compute the magnitude of F. Remember, these…
