Lab Setup: Assemble the Beam Bending Lab Kit & Open the Worksheet Working in a team of two, open the Beam Bending Lab Kit and examine the contents. If your Boam Bending Lab apparatus is not assembled, then assemble the parts to match Figure 9. The following components are included in your kit: • Clamp - used to securely hold the fixed end of the vertical cantilever beam Vertical Cantilever Beam - made of different sizes, shapes, and materials, including Aluminum e Copper (rectangular beam) 0 Copper (closed square heam) Unknown Dial Indicator - a precision instrument used to accurately measure beam deflection Pulley - transmits the vertical force of the weights to a horizontal force on the beam Weight Holder - holds up to ten weights Extra Weights - ten weights are supplied with each lab kit (50 gm.cach) (1) a 5/32" llex wrench (T-shaped tool) # Dal Indical Pule Wala Beam Waynt HO Extra vagnis
