A commercial suspended window cleaning platform has a mass of 1600 kg, is 5.00 m long and suspended by ropes at each end. b) If his partner, who weighs 850 N, were to stand 1.00 m from the other end, along with the equipment and first washer, would the ropes remain intact assuming that the system has a rating of 5000 N above the weight of the platform? Place both tensions and your yes or no answer here

Solution

balancing moment(r X F) about one end of platform,

(1 * 850)   + (5/2 * 1600 * 9.8) - (5 * T2) = 0

T2 = 8010 N

now balancing forces in vertical direction,

T1 + T2 - m1g - m2g = 0

T1 + 8010 - 850 - (1600 x 9.8) = 0

T1 = 8520 N

Yes.
