Q.2) The composite L-shaped object shown below is composed of two prismatic homogenous bars. Bar 1 is steel with density 7850 kg/m³, and bar 2 is titanium with density 4500 kg/m³. Determine (a) the center of gravity of the L-shaped object, and (b) its mass moment of inertia about the y centroidal axis obtained in part (a). ix 240 mm 1 40 mm 80 mm 2

The 24-kg uniform thin hollow square plate is pinned at point O, and its side L = 0.3 m. Determine its mass moment of inertia / (in kg•m²) about point O. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s². M Your Answer: Answer

Given the hanging plate as shown, made of a metal with a weight of 100 lb/ft², determine: a) the moment of inertia of mass of the plate about an axis perpendicular to the page and passing through the centroid b) the moment of inertia of mass of the plate about an axis perpendicular to the page and passing through the hanging corner 3.5 ft 3.5 ft 1.5-ft diameter hole

4) Please determine the mass moment of inertia of the steel body that shown in the figure with respect to the Y (vertical) axis. Dimensions are in millimeters. Density of the steel body is 7800 kg/m³. (L = 100) R20 Y axis 30
