WebSolution: Let us first calculate the limiting and kinetic friction between various surface. Between 3 kg and ground: f (l1 ) =f (k1 ) = μ 1 (2+3)g=0.1×5g=5N Between 2 kg and 3 kg: f … WebApply the condition of static equilibrium to the block. We have 2 F − mg sin θ − mg cos θμk = 0. The term 2 F comes from a force analysis in which we see that there are two segments of rope pulling equally on the block. We then solve this equation for F . Answer: F = (1/2) mg (sin θ + μk cos θ ) Hint and answer for Problem # 8

WebWith an incline that is frictionless and you have a block on it the block's weight is directed strait down but the normal force is perpendicular to the incline so when you add the force vectors you end up with a net force parallel to the incline pointing down and this is what causes the block to slide down the incline.

The vertical interlayer on the right side of block (i, j) is taken as an example for the determination of above-mentioned coefficients.The displacement of the left boundary (x 1 = − l x) of the interlayer should be … WebFriction will always oppose the direction of slipping at the contacting surface. To de-termine this direction, consider how the system would move in the absence of friction with this known as the direction of "impending motion". Consider the following steps (the OK method) for solving equilibrium problems with fric-tion: 1. FBDs. marine forecast grand isle
