Students are introduced to the five fundamental loads: compression, tension, shear, bending and torsion. They learn about the different kinds of stress each force exerts on objects.

Through a series of three lessons, each with its own hands-on activity, students are introduced to 1) forces, loads and stress, 2) tensile loads and failure, and 3) torsion on structures—fundamental physics concepts that are critical to understanding the built world. The associated activities engage students through experimenting with hot glue gun sticks to experience tension, compression and torsion; the design of plastic chair webbing strips; and problem-solving to reinforce foam insulation "antenna towers" to withstand specified bending and twisting.

This lesson focuses on torsion as a force acting upon structures. Students will have the opportunity to design something to withstand this force.

This is what our friend, Mr. Rogers has taught us. Life lessons of love and compassion for all. 

Open textbook in statics and dynamics for engineering undergraduates. Covers particles and rigid bodies (extended bodies), structures (trusses), simple machines, kinematics, and kinetics, as well as introductory vibrations. Includes text, videos, images, and worked examples (written and video).

This course provides an introduction to the mechanics of solids with applications to science and engineering. We emphasize the three essential features of all mechanics analyses, namely: (a) the geometry of the motion and/or deformation of the structure, and conditions of geometric fit, (b) the forces on and within structures and assemblages; and (c) the physical aspects of the structural system (including material properties) which quantify relations between the forces and motions/deformation.

The “small wonders” to which our course will attend are moments of present time, depicted in the verbal and visual media of the modern age: newspapers, novels and stories, poems, photographs, films, etc. We will move between visual and verbal media across a considerable span of time, from eighteenth-century poetry and prose fiction to twenty-first century social networking and microblogging sites, and from sculpture to photography, film, and digital visual media. With help from philosophers, contemporary cultural historians, and others, we will begin to think about a media practice largely taken for granted in our own moment.

Students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Popsicle sticks and hot glue, student teams design, build and test a simple tower crane model according to these principles, ending with a team competition.

Students reinforce an antenna tower made from foam insulation so that it can withstand a 480 N-cm bending moment (torque) and a 280 N-cm twisting moment (torque) with minimal deflection. During one class period, students discuss the problem, run the initial bending and torsion tests and graph the results. During the following class periods, students design, construct and test sturdier towers, and graph the results.
