Problem 6-95

The nail cutter consists of the handle and the two cutting blades. Assuming the blades are pin connected at B and the surface at D is smooth, determine the normal force on the fingernail when a force of 1 lb is applied to the handles as shown. The pin AC slides through a smooth hole at A and is attached to the bottom member at C. 1.5 in. A D C B 1 lb 1 lb 0.25 in. 0.25 in. Prob. 695

Step-by-Step Solution:
Step 1 of 3

Wednesday, April 20, 2016 Week 10 Associative Learning (Conditioning) - There is a suggestion that learning concepts are linked to motivated behavior Learned Motives - There are three types of learned motives: Classical Conditioning, Operant / Instrumental Conditioning, and Observational Learning Classical Conditioning - An example of this would be how I sprayed Professor Magalis with a water bottle most of the time I read the word “board” from a list. Now the word board causes him to rapidly blink his eyes and ﬂinch • Reﬂexes are associated with new stimuli - Pavlov is only one example of this: he studied dogs and their salivation pattern, even surgical suturing a ﬁstula in the dog’s mouths to collect saliva! • The most well known of his research examples is the dog salivating to a bell. He would start a metronome anytime he would feed his dogs, and the smell of food would make them salivate; over time the dogs would begin to salivate at the sound of the bell alone, having associated the metronome ticking with food - The original stimulus of the spray to the eyes is known as the unconditional stimulus, which caused the unconditional response of blinking and ﬂinching. - The neutral stimulus of the word “board” presents an orienting response, or simply capturing some attention. - The neutral stimulus is then paired with the spray to the eyes, or unconditional stimulus, and the combination resulted in the blinking or unconditional response - IF AND ONLY IF the word “board” is presented alone (without the spray) and it produces a partial blink or startle, only then would we state that classical conditioning has occurred. 1 Wednesday, April 20, 2016 - Eventually the neutral stimulus becomes a predictor of something which elicits a response, therefore the “neutral stimulus" is renamed as a “conditional reﬂex”, which elicits the “conditional response”. • Note: When the association is not practiced over time, then the conditional stimulus will produce a weaker and weaker conditional response, a process known as extinction • When Professor Magalis ﬂinched to the word “hoard”, and other words rhyming with “board”, we know this as a generalization of stimulus. In other words, the conditional response is associated with similar things which become weak stimuli for the conditional response. - Remember, NEUTRAL STIMULI DOES NOT DO NOTHING! It is attention grabbing, eliciting an orienting response Operant / Instrumental Conditioning - Reinforcement / Punishment motivates behavior - Behavior is altered by its consequences - The consequences of a response motivate the future probability of that response - Example Used: Potty training. In particular, our Professor’s Winnie the Pooh potty from infancy • In this scenario, the potty is dubbed the discriminative stimulus • The discriminative behavior can then elicit a response - The proper toilet training behavior, known as the operant • This then leads to praise (a positive reinforcer), which increases the frequency of the response which again increases the frequency of praise 2
