PLEASE RATE AS THE BRAINLIEST ANSWER! THANK YOU! :)
Answer:
a) Fc = 4.15 N, Fi = 435.65 N, (F1)a = 640 N, and F2 = 239.6 N,
b) Ha = 1863.75 N, nfs = 1 , length = 11.8 mm
Explanation:
Given that:
γ= 9.5 kN/m³ = 9500N/m3
b = 6 inches = 0.1524 m
t = 0.0013 mm
d = 2 inches = 0.0508 m
n = 1750 rpm
L = 9 ft = 2.7432 m
Ks = 1.25
g = 9.81 m/s²
a)
b)
dip =

Hope I helped and good luck with school. Bye!
Answer:
It will take 40 seconds to catch the speeding car
Explanation:
Initial speed of the patrolman = 55 mph
after one minute speed of patrol man = 115 mph
now acceleration of patrolman is given by
now at this acceleration the distance covered by patrolman in "t" time is given as
now we know the speed of the speeding car is given as
now in the same time distance covered by it
now since the distance covered is same
