Si sessions: t 6:00-7:30, th 5:00-6:30 (228 coates) Office hours: t 4:30-5:30, w 10:30-11:30 (allen 39) "physicists define stress as force per unit area. The rest of humanity defines stress as physics. " Nsl problems: multiple objects in connected systems, multiple objects in contacted systems. Announcements: homework 4 &5 is due tomorrow! Two blocks are in contact on a frictionless table. A horizontal force is applied to the larger block, as shown in fig. The figure shows four penguins that are being playfully pulled along very slippery (frictionless) ice by a curator. A 4. 0 kg block a and 6. 0 kg block b are connected by a string of negligible mass. Force fa on block a; force fb acts on block b. A tin of antioxidants (m1 = 1. 0 kg) on a frictionless inclined surface is connected to a tin of corned beef (m2 = 2. 0 kg).
