The 250-lb concrete block A is released from rest in the position shown and pulls the 400 lb log up the 30" ramp. Plot the velocity of the block as it hits the ground at B as a function of the coefficient of kinetic friction u, between the log and the ramp. Let uk vary between 0 and 1. Why does the computer not plot results for the entire range specified? 400lb 250lb A 30 deg 20

Question

Transcribed Image Text:The 250-lb concrete block A is released from rest in the position shown and pulls the 400 lb log
up the 30' ramp. Plot the velocity of the block as it hits the ground at B as a function of the
coefficient of kinetic friction u, between the log and the ramp. Let ux vary between 0 and 1. Why
does the computer not plot results for the entire range specified?
400lb
250lb
A
30 deg
20'
Hints:
-- Model the system as a dependent motion analysis and derive acceleration equations in terms of
the unknown quantities
-- Use MATLAB to solve this system of equations (you'll need one equation for each unknown!)
-- Define uk as a range in MATLAB from 0 to 0 in 0.01 increments
-- Plot the function of the velocity for the block as it hits the ground
