# The crate has a mass of 130 kg

8.17 A uniform crate of mass 30 kg must be moved up along the 150 incline without tipping. Knowing that the force P is horizontal, determine (a) the largest allowable coefficient of static friction between the crate and the incline, (b) the corresponding magnitude of the force P. Fig. "8.17A Crate on an Accelerating Truck. A 50.0-kg crate rests on the bed of a truck as shown in . The coefficients of friction between the surfaces are . and . Find the frictional force on the crate when the truck is accelerating forward relative to the ground at (a) 2.00 m/s 2, and (b) 5.00 m/s 2.

The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 130 kg. The cable is then wound ontoa hollow cylindrical drum that is mounted on the deck of the crane.The mass of the drum is 150 kg, and its radius is 0.76 m.

The coefficients of friction between all surfaces of contact are 0.20sm = and .15.km = If 40 NP = , determine (a) the acceleration of block B, (b) the tension in the cord.
A 1-kg mass at a height of 1 meter has a potential energy of 1 Joule. A 1-kg object falls from a height of 10 m to a height of 6 m. The final potential energy of the object is approximately 40 J. If work is done on an object by a non-conservative force, then the object will either gain or lose potential energy. 8.

The uniform crate has a mass of 150 kg. If the coefficient of static friction between the crate and the floor is $\mu_{s}=0.2,$ determine whether the 85 -kg man can move the crate. The coefficient of static friction between his shoes and the floor is $\mu_{s}^{\prime}=0.4 .$ Assume the man only exerts a horizontal force on the crate.
Sep 23, 2019 · The smaller top crate has a mass of m1 = 24 kg and the larger bottom crate has a mass of m2 = 86 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is μs = 0.79 and the coefficient of kinetic friction between the two crates is μk = 0.62.
Important: The slug is the base unit for mass in the English system, but the more common unit for mass is the Pound Mass (lbm).Under standard Earth gravity, 1 lbm weighs 1 lbf and therefore the term "pound" is usually used for both mass and weight in the English system. MASS Conversions 1 lbm = 0.45359237* kg (exact conversion) 1 kg = 2.2046226 lbm 1 slug = 32.1740486 lbm
A cord of mass 0.75 kg is stretched between two supports 30 m apartIf the tension in the cord is 130 N , how long will it take a pulse to travel from one support to the other? 3-63. The crate has a weight of 300 lb. Determine the tension developed in each cable...
The uniform crate has a mass of 130 kg . The coefficient of static friction between the crate and the floor is µs = 0.2. The coefficient of static friction between the man's shoes and the floor is µ's = 0.45. Assume the man exerts only a horizontal...
459. A ladder 4m long having a mass of 15 kg is resting against a floor and an wall for which the coefficients of static friction are 0.30 for the floor to which a man having a mass of 70 kg can climb without causing the plank to slip if the plank makes an angle of 40 degrees with the horizontal. a. 2. b. 1. c. 2.5. d. 3
A person with a mass of 120 kilograms has an Earth weight of 1176 Newtons which is 264 pounds. A person with a mass of 120 kilograms would weigh 196 Newtons on the Moon which is 44 pounds. 2.
