Abstract This paper deals with transverse impact on beams the mass of which is of importance. Experimental results are presented for comparison with theory. Impacts which appear single to the eye are shown to consist in reality of several blows in quick succession. Section 1 of the paper traces the historical development of this subject by discussing the investigations of Young, Hodgkinson, Cox, Saint Venant, and Timoshenko. Section 2 treats a simplified system in which a concentrated mass strikes a smaller concentrated mass having a “soft” spring restraint. For elastic impact, theory predicts for the struck mass a path composed of sinusoidal elements separated by instantaneous blows. For inelastic impact it predicts a joint harmonic motion. Records of the paths of both masses were obtained experimentally. Section 3 of the paper uses Timoshenko’s method of combining local deformation of the contact region with lateral vibration of the beam. An experimental investigation of maximum contact pressure and of blow duration gives what is believed to be the first confirmation of this theory. Section 4 describes an experimental determination of flexural stresses in elastic and inelastic impact on a 3-in. I-beam by the use of a Westinghouse magnetic strain gage. The indication is that stresses may be higher than those calculated by the usual approximations.

Service marketing focuses on service encounter stimuli, such as the servicescape, employee interactions, the core service, and other customers. The studies that have focused on other customers’ role as a social component of the service environment have led to the development of a comprehensive measure of other customer perception. Thus, based on the social impact theory, attraction theory and the theory of uniqueness, the study analysed the effect of Other Customer Perception (OCP), Need for Uniqueness (NFU and their interaction on service experience and revisit intention by employing a scenario-based quasi-experimental research design with a sample of 127 job holder postgraduate management students using convenient sampling technique. The study employed MANOVA GLM model and concludes that while the impact of consumers’ perceptions of other customers’ similarity does influence service experience of the customers, demonstrating that not only the restaurant itself, but also the entities in the surrounding network such as other customers have an impact on service experience and their revisit intention. Therefore, other customer effect, which works as a basis for service experience and revisit intention, should not be neglected when designing the surroundings in restaurant settings.
