Week 11 Challenge

SOLUTION 1.

1. Friction load determination

VERTICAL FORCE =125 KN

TAKE FRICTION COEFFICIENT =0.3

ASSUMPTION

ALONG THE PIPE -RESTRAINED IS THERE

TRANSVERSE-NO RESTRAINT

ONLY 10 PERCENT IS CONSIDERED FOR TRANSVERSE

LONGITUDINAL =125*0.3=37.5 KN

TRANSVERSE =125*0.1=12.5 KN

If TEFLON pad is used between shoe and pipe support.

TEFLON =N=0.1

IF TEFLON PAD IS USED =LONGITUDINAL=125*0.1KN =12.5 KN
