Answer:
power = 49.95 W
and it is self locking screw
Explanation:
given data
weight W = 100 kg = 1000 N
diameter d = 20mm
pitch p = 2mm
friction coefficient of steel f = 0.1
Gravity constant is g = 10 N/kg
solution
we know T is
T = w tan(α + φ )
...................1
here dm is = do - 0.5 P
dm = 20 - 1
dm = 19 mm
and
tan(α) =
...............2
here lead L = n × p
so tan(α) =
α = 3.83°
and
f = 0.1
so tanφ = 0.1
so that φ = 5.71°
and now we will put all value in equation 1 we get
T = 1000 × tan(3.83 + 5.71 )
T = 1.59 Nm
so
power =
.................3
put here value
power =
power = 49.95 W
and
as φ > α
so it is self locking screw

Answer:
1. 0.50
2. 0.75
3. 0.65
Explanation:
1. For the bid being successful with a 50-50 chance, we have the probability:
50/(50 + 50) = 50 / 100 = 0.50
2. Given the request for additional info:
Probability = probability of request and successful / probability of successful
= 75 / 100 = 0.75
3. We will evaluate the probability of being successful given its request
We will use the Bayesian theorem
= [P(request | successful) * P(successful)] / [P(request | successful) * P(successful) + P(request | unsuccessful) * P(unsuccessful)]
= ( 0.75 * 0.5) / (0.75 * 0.5 + 0.4 * 0.5)
= 0.65
