Part 1 Your Answer Correct Answer Correct Consider a point in a structural member that is subjected to plane stress. Normal and shear stresses acting on horizontal and vertical planes at the point are shown. Assume stress magnitudes of S - 55ksi, 5-15 ks, and S. - 14 ksi. m. Construct Mohr's circle for this state of stress on paper and use the results to answer the questions in the...

Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...

A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....
