Answer:
The tension in the cable that lifts the elevator = 2204 N
Step-by-step explanation:
Tension in cable acting upward = T
Weight of lift acting downward = W = mg
= (190)(9.8) = 1862 N
Total force acting in vertical direction = ∑Fy = T - mg
Force applied to move elevator upward = F = ma
=(190)(1.8) =342 N
Total force acting in vertical direction = Force applied to move elevator upward
T - mg = ma
T = mg + ma
T= 1862 +342
T = 2204 N
Answer: Tension =1520 N
Step-by-step explanation: Given:
Mass of elevator=190kg
Acceleration of elevator=1.8m/s^2
Acceleration due to gravity =9.8m/s^2
Weight acting downward=W=mg
W= 190Kg×9.8m/s^2
W=1862N
Upward force is Tension
EFy=may
+ is up
- is down
T - 1862=190(1.8)
T=1862-342
T= 1520N
