Good morning,

can you help me solving those questions

Part A A thin, rectangular sheet of metal has mass M and sides of length a and b. Use the parallel-axis theorem to calculate the moment of inertia of the sheet for an axis that is perpendicular to the plane of the sheet and that passes through For related problemsolving tips and strategies, you may want to one corner of the sheet. view a Video Tutor Solution of Using the parallel-axis theorem. Express your answer in terms of the variables M, a, and b. AEd I =Part A A slender rod with length L has a mass per unit length that varies with distance from the left-hand end, where x = 0, according to dm/dx = yx, where y has units of kg/m. Calculate the total mass of the rod in terms of y and L. For related problemsolving tips and strategies, you may want to Express your answer in terms of the variables y and L. view a Video Tutor Solution of Uniform sphere with radius r, axis through center. OVO AEd M = Submit Request Answer V Part B Use I = J'r' d'm to calculate the moment of inertia of the rod for an axis at the left-hand end, perpendicular to the rod. Use the expression you derived in part A to express I in terms of M and L. Express your answer in terms of the variables M and L. IVO AED C : ] ? I =Part C Repeat part B for an axis at the right-hand end of the rod. Express your answer in terms of the variables M and L. AEQ C U I =V Part A A circular saw blade with radius 0.195 m starts from rest and turns in a vertical plane with a constant angular acceleration of 2.00 rev / s' . After the blade has turned through 155 rev, a small How far does the piece travel horizontally, from where it broke off the blade until it strikes the floor? piece of the blade breaks loose from the top of the blade. After Express your answer with the appropriate units. the piece breaks loose, it travels with a velocity that is initially horizontal and equal to the tangential velocity of the rim of the blade. The piece travels a vertical distance of 0.820 m to the ? floor. 1 = Value Units Units input for part AV Part A A computer disk drive is turned on starting from rest and has constant angular acceleration. If it took 0.560 s for the drive to make its second complete revolution, how long did it take to make the first complete revolution? Express your answer with the appropriate units. LA ? t = Value Units Submit Request Answer Part B What is its angular acceleration, in rad/s? ? Express your answer in radians per second squared. AEQ rad/s2 a =V Part A As an intern at an engineering firm, you are asked to measure the moment of inertia of a large wheel for rotation about an axis perpendicular to the wheel at its center. You measure the What is the moment of inertia of the wheel for this axis? diameter of the wheel to be 0.920 m. Then you mount the wheel Express your answer with the appropriate units. on frictionless bearings on a horizontal frictionless axle at the center of the wheel. You wrap a light rope around the wheel and hang an 8.20 kg block of wood from the free end of the rope, as 0 in (Figure 1). You release the system from rest and find that the HA block descends 12.0 m in 4.00 s. I = Value Units Submit Request Answer Figure Submit Request Answer Provide Feedback A B
