Administrative n Today - distribute m.c. answers from exam 2 u versions of better/worse 10 pt.

Some mentioned 'an ethical dilemma', but few took it a step further to integrate class materials (if you could have written the same answer without attending class, you probably didn't score as high). 3

n d) Laws: u Mention of minimum requirements being met, but not always enough to protect the people. May mention and discussion of limitations of tort and/or contract law (tying it together to describe what might be limits for what the residents have the power to do, given their dissatisfaction). n e) What's the problem? u virtually everyone got these 2 points. n f) Better to place near your home?

Labor and Technology video - Modern Times - Charlie Chaplin 18th century - Factories –labor shift into factories –mechanization, many people needed at 1 site –however, no longer need as many highly skilled people to make things –factories located near streams and rivers- power 6

Mass Production and Line-Assembly First - Henry Ford - Ford Auto - Model T A car for the masses –inexpensive, simple and easy to make Produce millions to allow cheaper prices began with a series of experiments –first, a rope, 250 feet long, a car chassis was pulled –140 assemblers, 150 ft. line; 177 assemblers, 300 ft line –time to produce a car reduced from 12.5hrs to 6hr to 3hrs to eventually only 93 min/car 7

The new factory included special purpose tools centralized decision making standardized parts - interchangeable large sheet metal stamping tools (presses) – ,000 cars/year (Detroit, Michigan) – ,000 cars/year (River Rouge, Ford) –1923 2,000,000 cars/year (River Rouge, Ford) ‘optimizing’ worker performance time and motion analysis workers timed with stop watch and unnecessary motions were eliminated 8
