Calculating effect of swinging loads

Occasionally there are physics lab demonstrations that I think are pretty awesome but that my students just think are "meh. The basic idea in this demo, which I used in my class at Southeastern Louisiana University, is to swing a mass around in a horizontal circle. But wait! There's a cooler part: By running the string through a vertical tube and attaching it to another mass, we can control the tension in the string. It's loads of fun.

Calculation of bed load based on the measured data of suspended load | SpringerLink

Paddy and Water Environment. This paper proposes a method for establishing both the velocity profile and concentration profile for suspended sediment based on measured data consisting of average velocity and average suspended sediment concentration in the river and the irrigation channel. In addition, a numerical model for computing suspended load and bed load was also developed for computing bed load transport rate when measurable load is available. In this study, bed loads for published laboratory and field sediment data were computed using the presently developed numerical model based on four different bed layer thicknesses. The numerical model developed in this study may be used to evaluate the validities of other bed load formulas.

The Physics of Swinging a Mass on a String for Fun

The effects of the swinging of loads pendulum effect travelling under a suspended crane were traditionally reduced if the operator had enough experience to manage load inertia movement during travel. Basic working principle The principle of the control of load swinging is based on the calculation of swing movement time and lifting height. ESP calculates and automatically corrects the to-and-fro movements of the hook suspended load.

The dynamic kinetic energy of a moving object, like a falling ball or a driving car, can be expressed as. In an impact - like a car crash - the work made by an impact force slowing down the moving object in a deformation equals to the work done by a spring force - and can be expressed as. The front of the car impacts 0. The dynamic energy in a falling object at the impact moment when it hits the ground can be calculated as.
