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.

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
