Asked by Kate
A large dam scraper , with a mass of 900kg , is used to build an earth dam by means of a winch system. The slope of the dam wall is 60° to the horizontal and is 18m long .The loading capacity of the dam scraper is 1,5m ^3 of soil and the density of the soil is 3200kg/m^3 . The tractive resistance of the dam scraper up the slope is 650N .calculate:
1.The tensile force in the cable of the winch to pull the loaded dam scraper up the slope.
1.The tensile force in the cable of the winch to pull the loaded dam scraper up the slope.

component of weight down slope = m g sin 60
m = ( 900 + 3200*1.5 ) kg
g = 9.81 m/s^2 or whatever you use on your planet
Tension = 650 + m g sin 60
m = ( 900 + 3200*1.5 ) kg
g = 9.81 m/s^2 or whatever you use on your planet
Tension = 650 + m g sin 60
