The arm of a crane is 15.0 m long and makes an angle of 70.0 degrees with the horizontal. assume that the maximum load for the crane is limited by the amount of torque the load produce around the base of the arm. what is the maximum torque the crank can withstand if the maximum load is 450 n. what is the maximum load for this crane at an angle of 40.0°

To find max torque you need component of force that is perpendicular to the direction of vector r. For second part just set the equation above equal to 2308 and solve for Fmax. Only difference is the angle

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
