Question 1132170


To be safe, the ratio of the narrowest {{{width}}} of a scaffolding tower to its {{{height}}} should not be less than {{{3:7}}} 

a) What is the safe maximum height for a scaffolding tower of base {{{2m}}} by {{{3m}}}?

given: {{{w:h=3:7}}}
 
tower of base {{{w=2m}}}

{{{2:h=3:7 }}}

{{{3h=14}}}

{{{h=14/3}}}

{{{h=4.666666666666667}}}

{{{h»4.7m}}}


b) I want to reach a height of {{{14m}}}. What should the minimum width of my scaffolding tower be?

{{{w:h=3:7}}}

if {{{h=14}}}

{{{w:14=3:7}}}

{{{7w=3*14}}}

{{{w=3*14/7}}}

{{{w=3*2}}}

{{{w=6m}}}
