can you solve part C?

Figure C 2 @1 "₁ B < 1 of 1 >
Transcribed Image Text:Figure C 2 @1 "₁ B < 1 of 1 >
Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁ = 0.60 in and the connecting rod (member BC) has a length of r2 = 5.05 in. The crankshaft rotates in the counterclockwise or positive direction. (Figure 1) Figure y 1 of 1 Correct Part B - Velocity of B Find the velocity of B, VB, when 0 = 18.0° and = 6.49° . The crank is rotating at 170 rpm (revolutions per minute). Express your answer in component form. Enter the x and y components of the velocity separated by a comma, to three significant figures in in/s. ► View Available Hint(s) VB = -3.30,10.2 i, jin/s Submit ✓ Correct Previous Answers Part C - Velocity of C 0 Find the magnitude of the velocity of C, vc, when the piston has moved to the new position = 30.0° and = 5.91°.
