PROBLEM2: The mass of the wooden block shown in Fig. P2.4 is 5 kg and the spring stiffness is 15,000 bullet weighing 0.2 kg is fired at a speed of 20 m/sec into the block and becomes Determine the resulting motion u(t) of the block. N/m. A embedded in the block.

A bolt needs to be tightened to a degree that is equal to a moment amounting to 60 N-mm. If a 14-inch cross wrench will be used, how much force should be applied on both ends of the wrench to tighten the bolt? If ϴ = 60 deg, find the following:a)x and y components of 900 lbb)x and y components of 500 lb

Problem 3: Now we will repeat the previous problem using the Cartesian method. Values: FA = 20 N FB = = 30 N ● α = 25° ● Use the Cartesian method to determine... a) the magnitude of the resultant force on the bolt. b) the angle made by the resultant, as measured relative to the positive x-axis. FA α FB
