Product Description:

Product Introduction and Application:

Gantry crane mainly used for outdoor goods yard, cargo, bulk cargo yard handling operation. Its metal structure like the door frame, bearing the main girder, the installation of two supporting feet, can be directly walking on the orbit to the ground, both ends can be overhanging cantilever girders.

Gantry crane with high space utilization, wider range of operation, adaptation of wide and strong commonality, its widely used in port yard.

Q:A crane lifts a 2.25 x 10^3 N bucket containing 1.15 m^3 of soil to a height of 7.5 mCalculate the work the crane performs.A 845 N sled is pulled a distance of 185 mThe task requires 1.20 x 10^4 J of work and is done by pulling on a rope with a force of 125 NAt what angle is the rope held?Help please, I am so lost, steps?! Thanks!
In the first case, the force is applied in the same direction as movement; work is simply force times distance moved: (2.25 x 10^3 N)(7.5 m) 16875 J In the second case, you can find the component of force in the direction of movement by dividing work done by distance moved: (1.20 x 10^4 J) / (185 m) 64.86 N To find the angle of the rope, draw a right triangle representing the force vectorsThe hypotenuse is the applied force equal to 125 NThe horizontal base is 64.86 NUse trig to find the angle: cos(theta) (64.86 N)/(125 N) theta 58.74 degrees
Q:A construction crane lifts a 1.6×103-kg beam at a steady speed of 1.4 m/sWhat is the crane’s power output?
The answer is 22kW as shown by the previous answer but this individual has used the wrong value for mm 1.6 x 10^3 and not 1.6 x 10^2 as shown.
Q:Find Tension in Cables AB and AC?
First you need the angle that AB makes with the verticalThis is found from; Tan(1) d/AB .25/4 1 3.576 degNow you focus on the knotThere is a tension T1 up along AB on the knotThere is a Tension T2 down along AC on the knotThere is a weight w5000 N vertically down on the knotSince the knot is at rest the vertical forces must balance and the horizontal forces must balanceThis gives you two eqs: Vertical Forces: T1Cos(3.576) T2Sin(20) + w Horizontal Forces T!Sin(3.576) T2Cos(20) Or T1(.998) T2(.342) + 5000 T1(.062) T2(.94) You have two eqs in the two unknowns, which you can now solve for the two unknowns T1 and T2These are the tensions asked forYou can finish it.

Q:My pc and laptop are connected via wirelessLaptop goes on internet when connected to pcSo atm both are connected and working but how can I share files between them?I can see they are connected and everything(i had to bridge wireless and local area connection to get everything to work) so what should I do to make it able to transfer files?If you need additional info please ask and check bit later i`ll add extra infotrying to find out how to do this whole day and really need help
Apples with Skin Banana Orange Peach Pear Raisins Strawberries Avocado Squash Bread Rice Black Beans (a lot of fiber) Those are just a few! Good luck!
Q:My husband and I are moving to Kadena ab in septI know the military will move our stuff but i read something that no oversized furniture such as king size bed etc and we recently gotten rid of our queen and got king size bed and are very comfortable with itI'm hoping it's just wrong Please tell me i don't have to down grade back to a Also, we were planing on getting most our furniture here before we leaveSo we want to make sure whatever we get here will fit, work out well over thereI'm sure they have nice things over there but we'd rather get our stuff here.Any advice?
if you end up off base , a K size bed will NOT fit in fact it may not fit in on base housing either at least one room in every Japanese home is tatami.and you cannot have anything overly large or heavy in these rooms, as they damage the mats.and they are expensive to replace the towers have smallish elevators and the free standing homes have narrow stairs leading to the bedrooms anything oversized( wall units, etc) will NOT fit anything bigger than a 46 in TV will have a hard time theres the whole current thing.
Q:A crane of mass M 1.00 · 10^4 kg lifts a wrecking ball of mass m 1200kg directly upward.Find the magnitude of the normal force exerted on the crane by the ground while the wrecking ball is moving upward at a constant speed of v 1.00 m/s.I'm confused because there is a constant speed, no acceleration, then how can i use the second law Fma?
Excatly rightSo you can set a 0Therefore F(net) 0 and all the forces must sum to zeroSUM(F(i)) 0 What forces are on the crane? In this configuration, there are only three significant forces: F(ball) + F(gravity) + F(normal) 0 You can easily calculate the force on the ball and the force due to gravity leaving the normal force as a single unknown.
Q:I am bored what should i do?
Have you ever had your PC or Mac stop working and have to reboot it? Yeah, everyone hasBut on a ship, when the shít is hitting the fan, you don't want to have to wait for your weapons to reboot As Michael stated so well, Manual backup is a great fallback.
