• Cross, Rod 2018-05-01 A simple throwing task is described to illustrate various aspects of projectile motion. The task was to throw a tennis ball in a waste paper bin about 2 m away. Success depends on skill, but it also depends on the physics of the problem. If the ball is thrown underarm, then success depends primarily on the throw speed, which must be controlled to within about 2%. The launch angle can be chosen within a wide range. If the ball is thrown overarm, then the launch angle is just as important as the throw speed. • Sitichoke Amnuanpol 2017-10-19 Oct 19, 2017.

[WRCA (United States) 2006-11-15 The article looks at types of rope for different applications of surface mining ropes.

The Wire Rope Corp. Of America (WRCA), a leading producer, has over the last three years introduced shovel hoist rope, a new line of dragline ropes and a new drag rope designed for reverse bend fairlead systems.

Each of these is discussed in the short article, with results from actual field use. • Vosloo, W; Morris, J; Davis, A; Giles, M; Wang, J; Nguyen, H T T; Kim, P V; Quach, N V; Le, P T T; Nguyen, P H N; Dang, H; Tran, H X; Vu, P P; Hung, V V; Le, Q T; Tran, T M; Mai, T M T; Le, Q T V; Singanallur, N B 2015-10-01 In high-density farming practices, it is important to constantly monitor for infectious diseases, especially diseases that have the potential to spread rapidly between holdings. Pigs are known to amplify foot-and-mouth disease (FMD) by excreting large amounts of virus, and it is therefore important to detect the virus quickly and accurately to minimize the spread of disease. Ropes were used to collect oral fluid samples from pigs, and each sample was compared to saliva samples collected from individual animals by detecting FMD virus RNA using real-time PCR. Two different experiments are described where groups of pigs were infected with different serotypes of FMD virus, either with or without vaccination, and unvaccinated pigs were kept in aerosol contact. The sensitivity of the rope sampling varied between 0.67 and 0.92, and the statistical agreement between this method and individual sampling ranged from substantial to moderate for the two different serotypes. The ease of collecting oral fluids using ropes together with the high sensitivity of subsequent FMD detection through PCR indicates that this could be a useful method to monitor pig populations for FMD virus infection.

With further validation of the sensitivity of detection of FMD virus RNA, this can be a cost-effective, non-invasive diagnostic tool. © 2013 Blackwell Verlag GmbH. • Van Zyl, M 2000-09-01 Full Text Available, the most important finding of this report ensued from a thorough analysis of 'cut-wire' tests. Very few rope samples from discarded non-spin ropes were, or could be, obtained for the establishment and verification of the discard criteria for non.-spin ropes. The effects of broken wires in non-spin ropes were therefore simulated by testing laboratory prepared specimens with selected wires cut in the outer and inner strands.

These tests were a continuation of work carried in two previous SIMRAC. • Wen-bin Gu 2014-06-01 Full Text Available The finite segment method is used to model the line throwing rocket system.

A dynamic model of line throwing rocket with flight motion based on Kane's method is presented by the kinematics description of the system and the consideration of the forces acting on the system. The experiment designed according to the parameters of the dynamic model is made. The simulation and experiment results, such as range, velocity and flight time, are compared and analyzed. The simulation results are basically agreed with the test data, which shows that the flight motion of the line throwing rocket can be predicted by the dynamic model. A theoretical model and guide for the further research on the disturbance of rope and the guidance, flight control of line throwing rocket are provided by the dynamic modeling. • Bossolini, Elena; Nielsen, Ole Wennerberg; Oland, Espen There is a trend within the oil and gas market to shift from steel wire ropes to fiber ropes for lifting, hoisting and mooring applications.
