Problem 17-88

The 100-kg pendulum has a center of mass at G and a radius of gyration about G of kG = 250 mm. Determine the horizontal and vertical components of reaction on the beam by the pin A and the normal reaction of the roller B at the instant u = 0 when the pendulum is rotating at v = 4 rad>s. Neglect the weight of the beam and the support.

Step-by-Step Solution:
Step 1 of 3

ENGR 121 B Lecture Notes for 10/31/2016 Spencer Kociba ● Calculating Standard Deviation ○ u=mean, N=number of elements in a vector N ○ SD= 1 * ∑(x(i) − u) √ N−1 k=1 ■ Take each element, subtract the mean and square it. Repeat this for all the elements in the vector and sum them. Divide by N-1 and take the square root ○ Function this_std=standard_deviation(vec) ○ Part 1 (calculating the mean) ■ sum=0 ■ For i=1:length(vec) ● sum=sum+vec(i) ■ End ■ this_mean=sum/length(vec) ○ Part 2 (calculation of SD) ■ For i=1:len
