The formula for this problem that we will be using is: F * cos α = m * g * μs where:F = 800m = 87g = 9.8 cos α = m*g*μs/F= 87*9.8*0.55/800= 0.59 So solving the alpha, find the arccos above. α = arccos 0.59 = 54 ° is the largest value of alpha
Asch (1956) found that group size influenced whether subjects conformed. The bigger the majority group (no of confederates), the more people conformed, but only up to a certain point.
