Friction sums mechanics
WebIn a standard coordinate system (with x oriented to the right), the sum of horizontal forces for the top block is. F − F s f = m 1 a. and for the bottom block. F s f = m 2 a. where F s f is the force of static friction. Solving for a in these two expressions, and then equating them, gives. F = ( m 1 + m 2) F s f m 2. WebFigure 14.30 The geometry used for the derivation of Bernoulli’s equation. We also assume that there are no viscous forces in the fluid, so the energy of any part of the fluid will be conserved. To derive Bernoulli’s equation, we first calculate the work that was done on the fluid: d W = F 1 d x 1 − F 2 d x 2.
