### Educational Content on Rope-and-Pulley System#### Problem DescriptionIn the scenario described in Figure 1, there is a man with a mass of 90 kg attempting to move a crate that has a mass of 160 kg. The coefficient of static friction (\(\mu_s\)) between the man's shoes and the ground is 0.4, and the coefficient of static friction between the crate and the ground is 0.3.#### Diagram ExplanationThe figure illustrates a man pulling on a rope connected to a pulley mechanism, which is attached to the crate. The pulley alters the direction of the force applied by the man. The angles involved are:- 30° between the rope and the horizontal line from point C to the crate- 45° from the vertical where the rope connects with the pulley#### Problem-Solving Parts**Part A**- **Objective**: Determine if the man can move the crate using the rope-and-pulley system.- **Options**: - The man can move the crate. - The man cannot move the crate.- **Answer**: The man cannot move the crate (Correct).**Part B**- **Objective**: Calculate the static frictional force (\(F\)) between the man's shoes and the ground, as well as the force needed to move the crate. This involves comparing it to the maximum static frictional force (\(F_{\text{max}}\)) that can be developed.- **Expression of Result**: Answers should be expressed in Newtons to three significant figures, separated by commas.- **Input Field**: Provide your calculated value for \(F_{\text{max}}\).This problem explores concepts of static friction, mechanics with pulleys, and the application of forces in a practical scenario. Students are encouraged to apply formulas relevant to static friction and force calculation to solve the given tasks.

When two surfaces contact and slide against each other, a frictional force is generated. Several factors affect frictional force: Surface texture and the force acting on it are the main factors affecting it.
