= Q8. The 3.1-kg, uniform crate starts from rest to slide down the inclined surface. If the coefficient of kinetic friction between the crate and the inclined surface is μk 0.12, determine the work done by friction to the crate if the crate has moved s = = 2.7 m. (Assume tipping over does not happen, and the slope is long enough.) Negative sign must be included if the work done is negative. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s². S 30°

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.
