1. A 100-lb force acts as shown on a 300-lb crate placed on an inclined plane. The coefficients of friction between the crate and the plane are u, = 0.25 and H = 0.20. 300 lb Determine whether the crate is in equilibrium, and find the value of the friction force. 100 lb

In the mid-20th century, the availability and the growth in power of digital computers led to the increase in the mathematical model in the field of engineering and science. The analysis of these detailed models needs to be increased.
