Answer:
Torque = 1191.68 N-m
Explanation:
Given data
mass m = 76 kg
standingdistance r = 1.6 m
Solution
we get here torque that si express as
torque = force × distance ................1
torque = r × F sin(theta)
and we know that
F = mg .........2
and g = 9.8 m/s²
put here value in equation 1 we get
Torque = 76 × 1.6 × 9.8 × sin(90)
Torque = 1191.68 N-m
Answer:
This is a PERT (Program Evaluation and Review Technique) question and the expected duration of completing this activity can be solved using the formula below.
Pert Expected Duration Estimate = ║Optimistic Duration + (4 x Most Likely Duration) + Pessimistic Duration║/6.
15 days = Most likely Activity Duration.
10 days = Optimistic Activity Duration
20 days = Pessimistic Activity Duration
Substituting these values, we will have
(10 +(4 X 15) +20)/6. The pert estimate is therefore calculated as 15 days
The expected duration of completing this activity = 15 days.
