Claim: The acceleration of the blocks is zero/small/negligible/ “<<g”. Evidence: The mass of block A is much greater than the mass of block B. Reasoning: See two-point examples above. ii. 1 point Now suppose the mass of block A is much less than the mass of block B. Estimate the magnitude of the acceleration of the blocks after release. Initially the rod is held in the horizontal position and then released. Calculate the initial angular acceleration. <br> <img src="https Two particles each of mass m are attached at end points of a massless rod AB of length l. Rod is hinged at point C as shown.

Since this is the weight of block I we can find its mass using the relationship between mass and weight: F = ma 65.33 N = m(9.80 N/kg), m = 6.666 kg = 6.7 kg (Table of contents) 45. Two crates, of mass 75 kg and 110 kg, are in contact and at rest on a horizontal surface ( Fig. 4-47). A 730-N force is exerted on the 75-kg crate.
A barbell consists of two small balls, each with mass 450 grams (0.45 kg), at the ends of a very low mass rod of length d = 35 cm (0.35 m). The center of the barbell is mounted on the end of a low mass rigid rod of length b = 0.525 m (see Figure), and this rod rotates clockwise with angular speed 100 rad/s.

Inserts were made to provide a place for the rod ends to be screwed in. All inserts were made out of solid steel stock and turned down to 0.555” outer diameter. The inserts were then cut to a length of 1” and drilled and tapped to fit the accompanying rod-ends. All of the frond rod ends were 3/8-24 and the back rod ends were 5/16-24.
