A uniform rope is suspended from the roof of a building. The rope breaks if the tension in the rope is greater than 700 N. A man of mass 50 kg climbs up the rope. Find the maximum acceleration with which he can climb up the rope (g = 10 m/s2)
Ariba and Ayaan decided to use nails and a thread to make a circle on the ground. Ariba took a thin rope of length 5 meters and tied nails on both ends of the rope. Ariba fixed one end of the rope in the ground and kept holding it. She gave other end of rope to Ayaan and asked him to draw a circle. Similarly Ayaan took a thin rope of length 3 meters and made a circle in a same manner. What will be the ratio of areas of these two circles?
Two persons are holding a rope of negligible mass horizontally. A 20 kg mass is attached to the rope at the mid-point, as a result, the rope deviates from the horizontal direction. The tension required to completely straighten the rope is (g = 10 m/s2)
A monkey of mass 20 kg is holding a vertical rope. The rope will not break when a mass of 25 kg is suspended from it but will break if the mass exceeds 25kg. What is the minimum acceleration with which the monkey can climb up along the rope? (g = 10m/s2)
A man ordered a length of rope by telephone from his nearest hardware shop. But when a worker in the shop brought the rope, he found that the man on the telephone had miswritten the order by interchange feet and inches. As a result of this, the length of rope received was only 30% of the length he had ordered. The length of the rope which the man ordered was between :

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. A gentleman was walking through an elephant camp. P. He spotted that the elephants weren’t being kept in cages or held by the use of chains.  Q. As the man gazed upon the elephants, he was completely confused as to why the elephants didn’t just use their strength to break the rope and escape the camp. R. Curious and wanting to know the answer, he asked a trainer nearby why the elephants were just standing there and never tried to escape. S. All that was holding them back from escaping the camp, was a small piece of rope tied to one of their legs. 6. The trainer replied, "When they are young and smaller, they are tied in these ropes which they are unable to break. By the time they grow bigger and strong enough to break the rope, they are already conditioned to believe that they can't break the ropes."
An object of mass 5 kg is attached to the end of a rope. If the rope is pulled upward with an acceleration of 0.30 ms-2, what is the tension in the rope?
A direct rope haulage pulls 8 tubs loaded with coal through an incline of length 500 m having an inclination of 1 in 6. Consider the following additional data.

Tare weight of tub = 500 kg
Hauling speed = 9 km per hour
Coefficient of friction between wheel and rail = $$\frac{1}{{60}}$$
Coefficient of friction between rope and drum = $$\frac{1}{{10}}$$
Mass of rope per meter = 1.5 kg
The minimum power required to haul the tubs in kW is
