A person is pushing on a uniform block of wood as shown in the figure and parameter table. The block of wood has mass 140 kg and a coefficient of static friction of Hs, w = 0.3. Assume the person only exerts a horizonatal force on the block of wood, and their shoes have a coefficient of static friction Hs,p = 0.4. What is the minimum mass the person needs to be able to move the block? Also, what is the maximum value of 4a, w that the wood could have and still slide instead of tip if pushed at the same location?

Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

3.2 Sliding blocks with friction* Mass MA = 4kg rests on top of mass Mg = 5 kg that rests on a fric- tionless table. The coefficient of friction between the two blocks is such that the blocks just start to slip when the horizontal force F applied to the lower block is 27 N. Suppose that now a horizontal force is applied to the upper block. What is its maximum value for the blocks to slide without slipping relative to each other?
