Question in HL10524 Questions
Gives a plot of a velocity-time graph using JSXgraph, and a description of the motion shown in the graph. The student is asked to calculate the acceleration at different stages of the motion, and the displacement at the end of the motion.
-
Find the area, first moment of area, and coordinates of a general spandrel. The area may be above or below the function.
-
Calculate the moment of inertia of a composite shape consiting of two rectangles about the x or y-axis. Parallel axis theorem is often required.
-
Simple geometry to introduce the three-force-body procedure.
-
An A-frame structure supporting a force and a moment. The feet are at the same vertical position, so taking moments at one foot yields the y component of the reaction at the other.
-
Use integration to find the centroid of an area bounded by a parabola, a sloping line, and the y-axis.
-
Identify errors in student-drawn free body diagrams of a frame.
-
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.
-
Write expressions for the moment of inertia of simple shapes about various axes.
-
Find the tension required to hold a pole at a specified angle.
-
Find the sum of two 2-dimensional vectors, graphically and exactly using the parallelogram rule.
-
Given the specifications of two vectors, draw the parallelogram representing their sum, then estimate length of the diagonal.
-
Determine the maximum load on a truss given two constraints. Truss includes zero-force members.

Solve for the internal force in three members of a truss.
-
Use the parallel axis theorem to find the area moment of inertia of a triangle and a rectangle about various axes.
-
Find moment of inertia of a shape which requires the use of the parallel axis theorem for a semicircle.
-
Find moment of inertia wrt the x- and y- axes for a shape made up of two rectangles.
-
Find moment of inertia and radius of gyration for a built-up beam made of two channels and two plates.
-
Find moment of inertia of a composite shape consisting of a rectangle and two triangles with respect to the x-axis. Shapes rest on the x-axis so the parallel axis theorem is not required.
-
Find centroidal moments of inertia and radius of gyration for a beam composed of two angle sections forming a box beam.
-
Find the centroid and the centroidal moments of inertia for a beam composed of a flat plate and two angle sections.
-
Find the centroidal moment of inertia of a sideways T shape. This requires first locating the centroid, then applying the parallel axis theorem.
-
Use a table of properties to find the Area Moment of inertia for simple shapes: rectangle, triangle, circle, semicircle, and quarter circle.
The parallel axis theorem is not required for any of these shapes. One situation requires subtracting a triangle from a rectangle however.
Distinguish between centroidal and non-centroidal moments of inertia.
-
Calculate reactions and shear and bending moment at a point for an overhanging beam with a constant or uniformly varying distributed load.
