To find the circumference of a round shaft (either outside dimension or inside dimension of a hollow shaft), multiply the diameter by Pi (C = Pi x D). Pi = 3.1416.
You cannot. The mass depends on the material of the shaft and that has not been specified.
3 meter shaft is connected to a motor to a generator calls for the use of the use of the shallow shaft with an inner diameter of 100mm and the outer diameter of 150mm.knowing that the allowable shearing stress is 85 Mpa . determine the maximum torque that can be transmitted a) by the shaft as designedb) by a solid shaft of the same weight the material density is7800kg/m^3 .
Cone crusher crushes materials by the working surface between the movable cone and fixed cone. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.
obelisk
cylinder row: this is one type of arrangement of cylinders in multi-cylinderengines in which the centre line of crank shaft journals is perpendicular to the plane containing the centre lines of engine cylinderscylinder bank: in this the centre line of the crank shaft journals is parallel to the plane having the centre lines of engine cylinders
why propeller shaft are made hollow
Depends on what you mean by "better". For the same dimensions, a solid shaft will be a bit stronger, but also a lot heavier. If you were to make a hollow shaft of the same weight, but a bigger diameter, it'd be a lot stronger than the solid shaft.
the hard hollow "backbone" of a feather
Because the load taking capacity of hollow shaft is more as the load per unit area is lesser due to the lesser cross sectional area.
Most of the force in a shaft is carried by the outer layers of the shaft, and very. very little by the center. By using a hollow shaft you get almost the same turning strength for a lot less weight and material.
tapper angle formula of shaft
You cannot. The mass depends on the material of the shaft and that has not been specified.
To reduce weight and for good heat disposal.
medullary cavity
The shaft of the bone, between the epiphyses, is called the diaphysis. It has a hollow central medullary cavity containing marrow.The shaft of long bones is called DIAPHYSIS
the reebok o stick is semi hollow so to say. from about a inch above the "o's" or holes inthe stick there is black foam in the shaft and blade for support and strength. from there up the stick is hollow for the rest of the shaft. the reason behind the holes in the shaft of the stick is for weight savings and strength. if you look closely at the holes they are not perfectly round they are oval and that is for strength as an arch displase stress better.
The formula for calculating weight of a solid shaft is dia x dia x length x 7.8 x 1000000. This formula is the most commonly used.
