PPT-Forces and equilibrium Forces and Equilibrium

Scalars and vectors Types of forces Resultant of forces Equilibrium of particles Scalar and Vectors Scalar a physical quantity that is completely described by a real number. 1. The story so far:. We found the constraint matrix and the null space matrix. We “cheated” a little bit in assessing the rank of the constraint matrix. but I have some confidence that it is actually full rank as found.

(3) the rotating blades of a ceiling fan, and . (4) the wheel of a bicycle that is traveling along a straight path at constant speed. . . Static Equilibrium: We can use this fact to find the conditions for "static equilibrium": the condition an object is in when there are forces acting on it, but it is not moving. . The conditions for static equilibrium are easy to state: the sum of the (vector) forces must equal zero, and the sum of the torques must equal zero: . A truss is a structure composed of slender members joined together at their end points. The members commonly used in construction consist of wooden struts or metal bars.. Assumptions for Design.. To design both the members and the connections of a truss, it is necessary first to determine the force developed in each member when the truss is subjected to a given. A particle is said to be in . equilibrium . if it remains at rest if originally at rest. , or . has a constant velocity if originally in motion. ..
