Exam (6 questions) in Getting Started
A collection of information and activities to introduce students to Numbas. There is some information on how Numbas works, information on how to write answers to mathematical expression and number entry parts, and a "test yourself" explore mode activity.
Note: This exam was written for students accessing Numbas exams through the Numbas LTI tool. Some of the information does not apply to exams accessed standalone or through a generic SCORM player.

Question in Engineering Statics
Given the moment of inertia of an area about an arbitrary axis, find the centroidal moment of inertia and the moment of inertia about a second axis.

Question in Christian's workspace
Consider a binary tree with $2^n$ nodes.
We give generators for the isomorphisms of the tree: at each nonleaf vertex, swap the branches descending from that node.
 What is the action of a given word?
 Write a word which produces the required isomorphism
 Which generators commute?
 What is the order of each generator?
 Write one of the (nonroot) generators in terms of the others.
 Which permutations of the leaves are possible?
 What is the order of the group of isomorphisms?
 What is the order of the quotient group obtained by identifying all the leaves of one branch?

Question in Engineering Statics
