A few weeks ago we had occasion to a 3,300-lb. steam hammer pair of shear legs, dismantl from the foundation and the renew part of the foundation under ^'e had no crane, so we set up a d the machine and lifted it back lifted the anvil block weighing 11 tons, all in two days, one day being spent in obtaining and set- ting up the shear legs and ... 48 MODULE III 15. Hydrogen free coke containing 85 % (weight) carbon and the rest inert materials is burned in a furnace. It is found that during combustion 5 % of the coke charged is lost unburned. The flue gas analysis shows 14.84 % CO2, 1.65 % CO, 5.16 % O2 and 78.35 % N2. The flue gas leaves the furnace at 500 K and 100 kPa. May 01, 2010 · AAC block is longer than CMU: 0.61 m versus 0.41 m, respectively, and while AAC is lighter per unit of weight, due to its larger size it may weigh as much as a medium weight CMU block. In general, AAC has a mass between 15.7 kg and 25.7 kg, while CMU can have a mass between 11.8 kg and 29.5 kg, depending on block size, aggregate composition and ... Page 3. Wilmington, N. C., Up-to-date. Progressive cities have never been the result of accident, but in variably their development has been the outgrowth of natural and artificial conditions very clearly defined and unquestionable in their existence and influences. A block weighing 40 newtons is released from rest on an incline 8 meters above the horizontal, as shown in the diagram below. If 50 joules of heat is generated as the block slides down the incline, the maximum kinetic energy of the block at the bottom of the incline is 1. 50 J 2. 270 J 3. 320 J 4. 3100 J APlusPhysics: WEP-Energy 84.

12.42 A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam (Fig P12.36). The beam is uniform, weighs 200 N, and is 6.00 m long; the basket weighs 80.00 N. (a) Draw a free-body diagram for the beam. constant of 100 N/m. P15.57 (a) The problem tells us that the plank and spring are at equilibrium when the plank is horizontal. Then: 0 00 22 L mg mg kx L x k W §· o ¨¸ ©¹ ¦ where x 0 is the equilibrium compression distance from the unstretched spring. The plank is then displaced upwards by a small angle, a distance: LsinT above equilibrium. Steel rod support- maximum stress (from Eq. 1-1) becomes ing a weight W Fmax W gAL W smax gL (1-5) A A A (b) To calculate the maximum stress, we substitute numerical values into the preceding equation. The cross-sectional area A equals pd 2/4, where d 8 mm, and the weight density g of steel is 77.0 kN/m3 (from Table H-1 in Appen- dix H).

If the coefficients of friction are μs = 0.5 and μk = 0.4, the magnitude of the frictional force on the block is:

Mar 19, 2010 · A steel block weighing 12N is pulled up an incline plane 20° above the horizontal by a constant force of 7.35 N which makes an angle of 10° above the inclined plane. The block stars from rest and is pulled 2.0m along the . physics mg N F worker 1.5 m 0.91 m q q (1) A 45-kg block of ice slides down a frictionless ramp 1.5 m long and 0.91 m high. A worker pushes up against the ice along the ramp so that the block slides down at constant speed. (a) What is the force applied by the worker? How much work is done by (b) the worker’s force? (c) the gravitational force on the ... 32 A rubber block weighing 60. newtons is resting on a horizontal surface of dry asphalt. What is the magnitude of the minimum force needed to start the rubber block moving across the dry asphalt? (1) 32 N (3) 51 N (2) 40. N (4) 60. N 33 The data table below lists the mass and speed of four different objects. Which object has the greatest ... 1) Weight (mg): horizontal component = 0 vertical component = (mass of block)(9.81m/s^2) 2) Normal force (N): horizontal component = mg cos 45 vertical component = mg sin 45 (I picked the angle as 45 since I have my coordinate system set with the x-axis level with the ground, and the normal force is perpendicular to the surface, is this correct?)A block of stone, 1.5 metres long, 1 metre wide, and 1 metre high, was manhandled into the depression. Monks with 19 musical instruments, consisting of 13 drums and 6 very long trumpets, were arranged in an arc of about 90 degrees, 63 metres from the bowl-stone. The drums, open at one end, were aimed at the stone block.

Nov 11, 2014 · Design and Construction CE Board Exam Nov. 1997A block weighing 200 N rests on a plane inclined upward to the right at a slope of 4 vertical to 3 horizontal. The block is connected by a cable initially parallel to the plane passing through a pulley which is connected to another block weighing 100N moving vertically.
