Static Friction Required to Keep the System from Moving (Two Boxes) Ok, logically, it must be that the static friction force of block A equal to the force of gravity on block B, so mass of block A is: m_A * 9.8 * 0.30 = m_B * 9.8 m_A * 2.94 = 2 * 9.8 m_A * 2.94 ...
B. Determine how the coefficient of kinetic friction varies with varying loads. 1. Analyze the forces on the sliding block-hanging mass system and find a way to measure the frictional force on the block, F K . • Draw a Free Body Diagram for the forces on the sliding block. Use a ...
The coefficient of static friction,µbetween two surfaces in the form of a plane, see diagram below, is to place a body on the plane, and gradually increase the angle of inclinationθof the plane until the body is just about to slide down the plane. The coefficient of static friction,...
We systematically investigated the waiting-time dependence of the maximum static friction force, Fs(tw), using the dynamics of driven vortices in a high-Tc superconductor as a model system. Fs(tw) was measured in La2 ? xSrxCuO4 thin films with different structures, sample sizes and pinning ...

The most common is the triboelectric effect, which is commonly considered the result of friction. Through this effect, when two objects are rubbed against each other, electrons from one will "jump" to the other, causing the build up of an electric charge. What is the best description of ...
The free-body diagram for the ladder in this situation is shown in Fig. 1. Both the wall and the floor exert frictional and normal forces at the points of contact with the ladder. We assume that the ladder has length L and is uniform so that the force of gravity can be considered to...
In their tests, the friction and stress equilibrium was discussed and the results demonstrate that the dynamic initiation fracture toughness of coal is about 13 times higher than the quasi-static value. Tang and Xu (1990) tried to measure the dynamic fracture toughness of rocks using single edge...
Do you know how to draw a free body diagram? You have three forces acting - one is the weight of the bar, the second one is the weight of the person, and the third one is the force at support 1 you need to find. May 1, 2007 #5 aliaze1 174 1 lol...yea i got it, ...
If you then write an equation for the net force which describes the objects as not sliding up or down, (then solve for the speed) then you would find a range of solutions for the speed corresponding to the range of values for the static friction force (which can be from -μsN to +...
