Amassless rod of length l connects three iron masses. if the first mass (at 0) has a mass of 1.90 kg and the second mass (at x = mass (located at the center of mass of the system) has a mass of 148 kg, what is the moment of inertia / for a free rotation about the center of mass? [hint: the moment of inertia will be a function of l. l) has a mass of 8.77 kg and the third

Determine the maximum r-value of the polar equation r =3+3 cos 0

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
