A 60 Kg crate is resting on top of a 45 Kg crate as shown in figure below. The top crate is attached to a wall by a cord, and a rope attached to the bottom crate passes around two fixed pegs. The coefficient of friction between the two crates is 0.4; between the crate and the floor is 0.5; and between the rope and the pegs is 0.3. Determine the minimum force Pmin needed to cause move the bottom crate. 60 kg 45 kg

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.

A box rests on a rough table, and is just about to slip when pulled by a string inclined at an angle to the table. If the coefficient of friction is 0-25, find the tension in the string (a) when=45, (b) when a angle of friction.
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
