Problem 1: A metal plate is used to hold three 250kg blocks as shown. a) Determine the magnitude and point of application of a single force that is equivalent to the system of 3 blocks shown. b) the plate is supported by 3 vertical reaction forces acting at points A, B, and C, determine the magnitude of these reaction forces.
Problem 2: Determine the normal force and friction force that are acting on the object shown. You can assume the object will not tip under the given loading. b) Is motion impending, occurring or not occurring?
Problem 3: a) Determine the minimum force F that must be applied in the direction shown to SLIDE the object. b) Using the result from part a, determine the height, h, above which tipping will occur BEFORE sliding. Note: F is directed parallel to the hill as shown. (If you cannot answer a, make a guess for F and continue with part b to ensure partial credit)
Problem 4: Determine the location of the centroid for the area shown below, dimension are given in mm. (Give your results relative to the coordinate system shown).
Problem 5: Determine the area and the moment of inertia about the given x-axis and y-axis for the regions shown below, dimensions are given in mm.
