Support and Connection Types - MIT

A roller support cannot provide resistance to a lateral forces. Imagine a structure (perhaps a person) on roller skates. It would remain in place as long as the structure must only support itself and perhaps a perfectly vertical load. As soon as a lateral load of any kind pushes on the structure it will roll away in reponse to the force.

Motion in a Vertical Circle - Georgia State University

Motion in a Vertical Circle. The motion of a mass on a string in a vertical circle includes a number of mechanical concepts. It must satisfy the constraints of centripetal force to remain in a circle, and must satisfy the demands of conservation of energy as gravitational potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as the mass moves ...

Chapter 5 Stresses In Beams - ncyu.edu.tw

The applied loads (such as F 1,F 2 and F 3 in Fig.5.1) lie in the plane of the symmetry and are perpendicular to the axis of the beam (the x-axis).The axis of the beam bends but does not stretch ( the axis lies some where in the plane of symmetry; its location will be determined later).

Chapter 4 - Beam Deflections - Dr. Z. M. Nizam

the design of beams another consideration is the value of the vertical deflections that will occur when such beam is loaded. This chapter is intended as an introduction to the analytical techniques used for calculating deflections in beams and also for calculating the rotations at critical locations along the length of a beam.


A truss is a structure composed of slender members joined together at their end points. A simple truss is a planar truss which begins with a triangular element and can be expanded by adding two members and a joint. For these trusses, the number of members (M) and the number of joints (J) are related by the equation M = 2 J – 3.

Pinoleum blinds are made up of small wooden twigs laid horizontally which are joined together by vertical threading. The resulting weave is, as a result, only flexible vertically and can be drawn upwards once manufactured as a roller blind or in a similar fashion to a Venetian blind.
