Your new mobile phone business is now approaching its first anniversary and you are able to step back and finally take a deep br
eath and consider positive changes that could be implemented. One of these changes is to transform you from a reactive maniac running around putting out fires, to a role model, achieving personal excellence. What specific steps will you use to make this transition? What specific programs will you put in place to help your key personnel do the same? Submit your paper to Drop Box 10.3.

Answer:
the minimum width is b= 0.1414m = 141mm
Explanation:
]given,
L= 4.25
w₀ = 5.5kN/m,
allowable bending stress = 7MPa
allowable shear stress = 875kPa
h/b = 0.67
b = ?
for a linearly distributed load, with maximum load intensity, w₀ of 5.5kN/m,
the maximum moment, M exerted by the timber is =
given h/b = 0.67, i.e h=0.67b
allowable bending stress = = 7000kPa
7000 = (6*6.37)/ (b *(0.67b)² ) = 38.21/0.449b³
3080b³=38.21
b³ = 38.21/3080 = 0.0124
b = 0.232m
h=0.67b = 0.67* 0.232 = 0.155m
for allowable shear stress = (3V)/(2bh)
875 = (3V)/(2bh) = (3x 7.79)/(2xbx0.67b)
875 = 23.375/1.34b²
1172.5 b²= 23.375
b² =0.0199
b= 0.1414m
h=0.67b = 0.67* 0.1414 = 0.095m
the minimum width is b= 0.1414m = 141mm
