Answer:
676 ft
Explanation:
Minimum sight distance, d_min
d_min = 1.47 * v_max * t_total where v_max is maximum velocity in mi/h, t_total is total time
v_max is given as 50 mi/h
t_total is sum of time for right-turn and adjustment time=8.5+0.7=9.2 seconds
Substituting these figures we obtain d_min=1.47*50*9.2=676.2 ft
For practical purposes, this distance is taken as 676 ft

Answer:
125pi W/m
Explanation:
This is the formula for heat transfer by convection
Q=hA(T2-T1)
Q=Power
h=convection coefficient
A=area
T2= temperature of melting point
T1=temperature of air
Area of tow rods
A=2*pi*D=2*pi*0.01=pi/50
Q=10*(´pi/50)(650-25)
Q=125pi W/m
