00-0.38m 680N 0.19m motor exerts up to 1854m (6) What is the maximum possible angular acceleration when lifting a 680N load?

1. A wheel tractor has a 200 HP engine. Calculate the available rimpull of this tractorif it is operating at an altitude of 1,000 m. above sea level, at an averagetemperature of 25oC, and at an average speed of 12 km/hr. Take rimpull efficiencyas 85%.2. The weight of the wheel tractor in Problem 1 is 30 tons and the weight on the drivingwheels is 50% of this weight. What is the maximum available rimpull if thecoefficient of traction is 0.25?3. What is the maximum grade that the tractor in Problems 1 and 2 can climb if it ismoving on a surface with a rolling resistance of 150 kg/ton?4. Assume that the tractor in Problems 1, 2, and 3 is moving down a 8% grade. Howmany minutes are necessary to accelerate to the average speed of 5 km/hr in firstgear? Use a rimpull reduction factor of 75% in your calculations.

Find the angle of banking for a highway curve of 300-ftradius designed to accommodate cars travelling at speed ofup to 120 mph, if the coefficient of friction between thetires and the road is 0.60. What is theminimum speed in miles per hour (mph) at which a carcan round the curve without slipping?

Please help me find force P in the problem

A three cylinder radial engine driven by a common crank has the cylinders spaced at120°. The stroke is 138 mm, length of the connecting rod is 252 mm andthe mass of the reciprocating parts per cylinder is 2.2 kg. Calculate the primary and thesecondary forces at crank shaft speed of 1500 rpm.

Aweight of 400 N is dropped through a height of 600 mm onto a closed coil compression spring which instantaneously compresses by 200 mm under the impact. The diameter of spring wire is 25 mm and mean diameter of coil is 200 mm. Find maximum instantaneous stress produced by impact, and number of coil in spring take G = 30 in/mm2

Given the shaft with multiple torques on it, calculate the internal torque developed in the BC segment: TBC = ____ N-m. If it is negative, please input the negative sign as well.

Repeat Problem 11.2-3 assuming that R= 10 kN · m/rad and L = 2 m.

The figure shows a steel bar being processed by a rolling mill. Given that P=80kN and r =0.016, determine the force F required to advance the bar at a constant speed.
