Question

The mass of a lift is 600kg. The max tensile force that the cable supporting the lift can withstand is 7kN. calculate the max upward acceleration allowed.

Answer 1

11.666666666666666666666666666667 m/sec2

Answer 2

can you please show your calculation?

Answer 3

what formulae did you use?

Answer 4

the answer is 1.867 m/s2. just dont know how to calculate it.

Answer 5

You sure? I get .86. Its a tension problem so it should be in equilibrium. I am getting .86 m/s2

Answer 6

are'nt you forgetting about gravity? 10
m/s2

Answer 7

1.867 is the answer in my book so should be right

Answer 8

T= W + ma= mg +ma

Answer 9

T= 7000N = 600 (10 +a)
70/6= 10 +a
70/6 -10 =a
11.67 -10= a
1.67= a

Answer 10

They used 9.8 not 10, so you do get the 1.87 m/s2

Answer 11

well done! thanks.
