The I-section has the dimensions (in mm) shown in the figure. Calculate the second moment of area about the X-X axis when D = 248 mm and W = 136 mm. Input your answer as a value only in (centimetre)4 to zero decimal place. W mm 15 mm X+ 10 mm X D mm 15 mm

Express F as a vector in terms of the unit vectors i, j, and k. Determine the angle between Fand the positive y-axis. Assume r, = 35 mm, ry = 60 mm, r, = 175 mm, F = 50 N. %3D Dimensions in millimeters No need to attach your solution.use the box to input your answer. Answer 9 * (1) в I х, >

Problem 3. Calculate the moment of inertia of the following area with respect to its y centroidal axis. PL 1/2X6 PL 3/8X8 PL 1/2X6 c Note 1 PL aXc PL = plate; a = thickness; c= longer dimension a and c are in inches. Note 2 For a rectangle with base = b and height = h, the moment of inertia with respect to its centroidal axis is equal to (1/12)bh³.
