Calculate theminimum force that must be applied by this arm to hold a package on the ramp. The ramp is at an angle of 0 29.5° with thehorizontal. The package has a mass of 5.25 kg. The coefficient of static friction between the ramp and the package is 0.405force:N.

A block whose weight is 31.6 N rests on a horizontal table. A horizontal force of 25.3 N is applied to the block. The coefficients of static and kinetic friction are 0.649 and 0.363, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s as the acceleration. Number Units

In an experiment designed to investigate the frictional forces between bodies, a force was applied to a block of wood lying on a flat metal surface, as shown. Applied force Block of wood It was observed that a minimum force was needed to move the block. The minimum force Fmin was measured for different blocks made of the same wood but with different masses M. The results of the experiment are shown in the table. M (kg) Fmin (N) 0.52 0.58 0.64 0.75 0.88 1.01 1.21 3.1 3.6 3.9 4.4 5.2 6.2 7.4 (a) Plot a graph of Fmin against M. (b) Use a linear regression analysis to fit the best straight line through the data points.

#1) Use Newton's Second Law Analysis to solve the following problem. , 1 - sketch and FBDs, 2 - write 0 down force equations in all dimensions, and 3 solve for requested variable. Two boxes, connected by a rope, are at equilibrium (need to consider friction on the incline). Box B is not touching the incline, it is just hanging from the outer rim of the pulley. Assume the magnitude of the tension force is greater than the magnitude of the wx component of mass A for part A (this should help you determine the direction of the static friction force). Draw the FBD for both box A and box B separately. Use N, for Normal Force, use fs for the static friction force, use proper variations of wx and wy for the weight components (two masses here, so they should have different labels not just wx and wy for both, you need to be able to tell them apart), and use T for the Tension Force. Somewhere in your work show what your variations of the magnitudes of wx and wy are in terms of the masses and g…
