একটি লিফটের ওজন `4000kg` যখন সাপোর্টিং তারের ঊর্ধ্বগামী টান `48000 N` হয়

An elevator weighs 4000kg When the upward tension in the supporting cable is 48000 N what is the upward acceleration? Starting from rest, how far does it rise in 3 seconds ?

A 60 HP electric motor lifts an elevator having a maximum total load capacity of 2000 kg. if the frictional force on the elevator is 4000 N, the speed of the elevator at full load is close to : ( 1 HP = 746 W, g = 10 ms ^( - 2 ) )

A train having 60 compartments is pulled by engine with a force 6xx10^(4) N. If mass of each compartment is 4000 kg the tension in the coupling between 40 th and 41st compartment is:

A string of length 0.5m and linear density 10^(-4) kg/m is stretched under a tension of 100 N. If the frequency of the vibration of the string is 4000 Hz, how many loops are formed on the string?

Natural length of a spring is 60 cm and its spring constant is 4000 N/m. A mass of 20 kg is hung from it. The extension produced in the spring is (Take, g = 9.8 m//s^(2) )

An electric motor of mass 40 kg is mounted on four vertical springs each having spring constant of 4000 N m^(-1) . The period with which the motor vibrates vertically is

Natural length of a spring is 60 cm, and its spring constant is 4000 N/m, A mass of 20 kg is hung from it. The extension produced in the spring is (take g=9.8m//s^(2) )

A lift can hold 2000kg, friction is 4000N and power provided is 60HP. (1 HP = 746W) Find the maximum speed with which lift can move up.

An elevator has full load capacity 800 kg. Frictional force on the elevator is 4000 N. If elevator is going down with constant speed 2.0 m/s, then the power applied by electric motor at full load is lose to : (1 HP = 746 W, g = 10 m//s^2 )
