121. We have friction in this direction, because clearly the ladder wants to slide like this, so the frictional force will try to prevent that, will be in this direction.

122. Because of the ice and the snow, it has less frictional force.

123. The dynamic interaction between an embedded object and surrounding media with a unilateral frictional contact interface is studied by time-domain boundary element method.

124. Based on reduced iron powder,[www.Sentencedict.com] this brake-block forms a composite of heterogeneous structure which contains certain quantity of frictional and lubricational elements.

125. So in this thesis, which is based on wet friction clutch of the mineral locomotive designed, design method, work performance and frictional heating of wet friction clutch are primarily studied.

126. Thirdly, the existence of the information transmit failure makes frictional unemployment among the under graduates.

127. Applying coat of grease or antirust oil on unpainted metal surface and every frictional part.

128. Viscosity: Viscosity is the crude oil in the flow caused by the internal frictional resistance, crude oil viscosity depends on temperature, pressure, dissolved gas and its chemical composition.

129. The relationship between dust emission rate and frictional velocity was analyzed too.

130. According to the analysis for failure reasons of vertical shaft wall in Linhuan Coal Mine, its main reason is longitudinal load produced by negative frictional force.

131. Behavior of an improved pseudo viscous frictional damper ( IPVFD ) was studied by testing and numerical analysis.

132. With the increase of frictional force, the direction ability of guardrail will be weak.

133. In the designing calculation of huge heavy loading manipulating equipments the frictional force should not be neglected.

134. In the absence of frictional energy dissipation, input work and output work are equal.

135. According to characters of geometrical shape and frictional force of steel ball, the practical mechanism with special function is designed by using steel ball composed of special construction.

136. It is moving, so sure, it's going to be accelerated so the frictional force is in this direction, has this value.

137. The load-settlement curve, the proportion between pile compression and pile top settlement, the distribution of axial force and lateral frictional resistance under vertical loads are obtained.

138. This paper investigates design, construction and performance tests of a thin disc piezoelectric clutch mechanism, including a driving frictional member and a driven frictional member.
