### Friction Sample Analysis on a Test Ramp

A friction sample is placed on a test ramp that pivots about a designated Point \( O \). When the end of the ramp is lifted to a height of \( h = 1.2 \, \text{ft} \), the sample just begins to slide. With the length of the ramp \( L = 3.5 \, \text{ft} \), the coefficient of static friction is best given by:

- a. 0.286
- b. 0.481
- c. 0.365
- d. 0.181

#### Diagram Explanation

The diagram accompanying the problem shows a ramp pivoting at point \( O \) on the left side. The ramp, represented as a straight line, is inclined at an angle due to the height \( h \). The length from point \( O \) to the point where the sample is placed is \( L = 3.5 \, \text{ft} \), while the height from the ground to the top of the ramp is \( h = 1.2 \, \text{ft} \). A rectangle on the ramp represents the sample, with a width \( W \) (though \( W \) is not used in this calculation). The problem requires determining the coefficient of static friction when the sample begins to slide at this configuration.

Question 3(a) The non uniform XYZ bar which weighs 155 kg has its centre of gravity G at a distance 4 m from X. This bar rests on a homogeneous crate P. The static coefficient of friction between the bar and the crate is 0.31 while the same between the crate and the floor is 0.22. Determine the mass of the lightest crate P (in kilograms) that can be used to support this non uniform bar in the position shown in Figure 3. The height of the crate is 4.32 m and the length of the bar is 8.59 m. 4 m 3 m - 1 m - Figure 3 Question 3(b) Take an example from everyday life where you can identify the application of the concepts we learn in the "Dry friction" module. Sketch this example and discuss about the effect of friction on that particular scenario. Sketch does not have to be drawn to a scale. (Description should be 250 words or less).
Consider the situation shown where a 15-kg box is to be held on a steep vertical slope by a cord that can withstand 80 N. Will the box be held or will the cord snap (i.e. exceed 80 N)? The coefficient of static friction between the box and slope is 0.3. Note: more sophisticated methods exist but do a simple analysis using statics alone and a little reasoning. 60
