1.The instrument used to measure a change in temperature . Bars AB and CD are made of A-36 steel and 2014-T6 aluminum alloy,respectively. When the temperature is at 75degreeF, ACE is in the horizontal position. Determine the vertical displacement of the pointer at E when the temperature rises to 150dwgreeF. ?
2.Force P is directed from point A(5,10,3) towards point B(1,-2,5) and has a magnitude of 15N. Vector Q=6i+2j-5k. When finding the projection of P onto Q what do you do with the 15N?
