1.7 Find the primary dimensions of each of the following terms. pV2 dA, where p is fluid density, V is velocity, and A is area. а.

1. The following equation describes the relationship between the maximum deflection of the end of a beam and the applied load. PL3 = 3EI a) If ð is the maximum deflection in inches, L is the length of the beam in inches, P is the load in pounds, and E is the Young's Modulus in pounds/in?, find the units for I (moment of inertia). b) The measured deflection for a specific beam under loading is measured to be .01 in. Convert this to millimeters.

Problem 6: Inputs: ● ● ● a = 600 mm b = 400 mm c = 200 mm F = 100 N The line of action of the force vector passes through points B and C. B X Z (a) Use the cross product to compute the moment about point A. For this part, you must use B in your vector formulation. F That is, compute MA = B x F. Express your answer as a vector and convert "mm" to "m". IB a A IC с (b) Now use a different position vector, r, in the cross product. This time use rc to to compute the moment about point A. For this part, you must use rc in your vector formulation. Compute MA = rcx F. Express your answer as a vector and convert "mm" to "m". c) Do your answers agree? Yes or no. F y
