A planar robot arm is constructed by using two rods as shown in Figure 8.6. Suppose that each of the two rods may telescope, that is, that their respective lengths l1 and l2 may vary between 1 and 3 units. Show that the set of states of this robot arm may be described by a smooth parametrized 4-manifold in R4.
2. TRADE SYSTEM (ITS) •Bilateral system of exchange of goods & services: 2 types of trade: 1. Merchandise trade primary goodsraw foods, fuels, fibers, minerals, water; manufactured goods anything processed. 2. Service trade mostly GN dominated vs GS. •Global trade flows: 1913—> $20 Bill = $55,000/day 2013—> $18.3 Trill = $50 Bill/day happened ^ because now countries are more interconnected •Outsourcing 3rd party is being paid to complete a job for the company contracting another company. •Offshoring sending business abroad. •Restoring companies returning back to homeland. •GN Has an Advantage in ITS: because of colonization GN has primary goods (produced by colonies/GS states). —
