Draw Shear and Bending Moment Diagrams for a simply supported beam with triangular loading

 Students must derive the shear and bending moment functions for beam loaded with a parabolic distributed load described with a loading function.  Diagrams are given, but the students must derive the equations by integration.

Find the reactions of a simply-supported beam with a trapazoidal distributed load.

When saving the data necessary to resume an attempt, Numbas only saves the values of variables which use the random number generator.

If you naively generate a large random sample in one variable, it'll be marked as a source of randomness so Numbas will save every value in the sample. Loading this value when you resume the attempt can be very slow.

Instead, you can generate a seed value in one variable and then use it with the seedrandom function in the variable that stores your random list. Only the value of the seed needs to be saved.

Shear and bending moment diagram for a beam loaded with an arbitrary parabolic distributed load described with a loading function.  Integrate to find reactions and equations for shear and bending moment.

Derive the expressions for the shear and bending moment as functions of $x$ for a cantilever beam with a uniformly varying (triangular) load.

The assessment has been designed to take no more than 2 hours to complete. You must submit the test by 10:00 am (UK time) on 13th May. Once you start the test, it has to be completed by 2 hours.

When answering the exam you should observe normal exam conditions and must not communicate/collude with other students taking the paper. The work that you submit must be your own work. Should you encounter IT difficulties that significantly affect your ability to complete this exam or when uploading your answer(s) you may submit a PEC detailing these.
