Abstract: Motion in two dimensions with one dimensional acceleration (projectile) is analyzed with component motions in coordinate system, whereas motion in two dimensions with two dimensional acceleration (circular motion) is analyzed with the help of component accelerations - tangential and normal accelerations.
Abstract: Objective questions, contained in this module with hidden solutions, help improve understanding of the topics covered under the module "Angular momentum".
Abstract: This lesson focuses on torsion as a force acting upon structures. Students will have the opportunity to design something to withstand this force.

Abstract: Introduction to statics and the mechanics of deformable solids. Emphasis on the three basic principles of equilibrium, geometric compatibility, and material behavior. Stress and its relation to force and moment; strain and its relation to displacement; linear elasticity with thermal expansion. Failure modes. Application to simple engineering structures such as rods, shafts, beams, and trusses. Application to design. Introduction to material selection. 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.
Abstract: Motion of projectile on an incline can be studied in terms of a new pair of coordinate axes with x-axis along the incline and y-axis along perpendicular to the incline.
