Next, consider the case where the block is suspended on an inclined surface by the same massless spring, as shown below. The free-body diagram for the block is also provided below. Notice that the surface makes an angle (0 ) of 22.0° and the force of friction, f points up the incline (as shown in the free-body diagram). What is the force of friction on the block if the spring is pulled up the incline by stretching it 0.520 m from its relaxed equilibrium length, assuming that the block is at rest?

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

Consider a 14.5 kg rectangular block of length 0.40 m attached to a spring with a
spring constant of 30.5 N/m.
The coefficient of static friction between this block and the surface is 0.310.

Next, consider the case where the block is suspended on an inclined surface by the
same massless spring, as shown below. The free-body diagram for the block is also
provided below. Notice that the surface makes an angle (0 ) of 22.0° and the force of
friction, f points up the incline (as shown in the free-body diagram). What is the
force of friction on the block if the spring is pulled up the incline by stretching it
0.520 m from its relaxed equilibrium length, assuming that the block is at rest?
Answer in units of newtons (N), with 3 sig figs.

You need to move a cubic crate across a rough floor. You pull the crate horizontally using a rope with force F, as shown in Figure 1. The weight of the crate is 700 lb:, its density is 180 lbm/fts, and the coefficient of static friction between the crate and the floor is 0.57. Write an expression for the maximum static friction force fmax (in lb:) as a function of the mass m of the crate. Use Excel to plot fmax(m). Calculate the average pressure of the crate on the floor, in psi. Calculate the minimum force F necessary for the crate to start moving, in lb;. F Figure 1. Moving a crate on a slope.
