4. A concrete weight of 125 kg is released from standstill and a log of mass 200 kg is moved along an inclined area of 30° to the horizontal.When the concrete weight is moved down 5 m, find that 1. What is the speed of the log? 2. What is the movement time of the concrete drum?
The crude-oil pumping rig shown is driven at 20 rpm. The inside diameter of the well pipe is 2 in., and the diameter of the pump rod is 0.75 in. The length of the pump rod and the length of the column of oil lifted during the stroke are essentially the same, and equal to 6000 ft. During the downward stroke, a valve at the lower end of the pump rod opens to let a quantity of oil into the well pipe, and he column of oil is then lifted to obtain a discharge into the connecting pipeline. Thus, the amount of oil pumped in a given time depends upon the stroke of the lower end of the pump rod. Knowing that the upper end of the rod at D is essentially sinusoidal with a stroke of 45 in. and the specific weight of crude oil is 56.2 lb/ft3 determine (a) the output of the well in ft3. /min if the shaft is rigid, (b ) the output of the well in ft3 /min if the stiffness of the rod is 2210 N/m, the equivalent mass of the oil and shaft is 290 kg, and damping is negligible.
A. Estimate the typical maximum horizontal distance that a person can throw a baseball. (Answer: 40m) B. Based on your estimate from part A. What is the speed of the baseball as it leaves the hand? v0= ? (m/s) C. If you could throw the baseball straight up at the same speed as in part B, how high would it go? hmax = ? D. The value of g on Venus is 8.9 m/s2. What horizontal distance can you throw a baseball on Venus if you throw it with the same initial speed as in part B? Rmax=?

A bug sits 2.2 cm from the center of a turntable that starts from rest and rotates 2.4 times in 1.8 seconds to reach a constant angular velocity, wf. Find the average angular velocity of the bug.
In a chain drive, the speed of the chain is not uniform and varies from a minimum value to a maximum value for every rotation or cycle of tooth engagement. If the ratio of the maximum value of the chain speed to its minimum value is 1.017322, determine the angle of articulation in degrees.

A projectile is launched at an angle of 45 degrees from the top of a 100 m tall cliff at 50 m/s. How high does the projectile fly above the bottom of the cliff? Use g = -10 m/s/s.
A great deal of effort, time, and money has been spent in the quest for a so-called perpetual-motion machine, which is defined as a hypothetical machine that operates or produces useful work indefinitely and/or a hypothetical machine that produces more work or energy than it consumes. Explain, in terms of the first law of thermodynamics, why or why not such a machine is likely to be constructed.
Given the figure before, when the displacement of block D is 360 ft, then the displacement of block A is closest to:
An automated storage/retrieval system has four aisles. The storage racks in each aisle are 40 ft high and 200 ft long. The S/R machine for each aisle travels at a horizontal speed of 400 ft/min and a vertical speed of 60 ft/min. If the pick-and-deposit time = 0.3 min, determine the throughput rate (loads moved/hr) of the AS/RS, under the assumption that time spent each hour performing single-command cycles is twice the time spent performing dual-command cycles, and that the AS/RS operates at 90% utilization.
