Place the assembled test frame on a work bench. 2. Fix the support and load cell to the respective positions as shown in the layout (Figure 1). 3. Build the frame using supports and joint bosses. 4. Fit the frame to the support using pins. 5. Ensure that the digital force display is ON. Connect the Mini DIN lead from the force input 3 on the digital force display to the socket marked force output. 6. With no load on the load cell, zero the reading using the control on the front of the load cell 7. Connect the strain gauges to the digital strain display matching the number on the lead to the number on the socket

8. Apply a preload of 100 N and again zero the load cell. 9. Carefully apply a load of 478 N and check if the frame is stable. Return the load to zero. 10. Apply loads 0 N to 578 N in increments of 100 N and note down the strain in three members in Table 1(Member strains in simple cantilever) 11. Make Table 2 (True member strain in simple cantilever) by subtracting all strains with the corresponding strain in 0 N load. 12. Table 3 records the experimental and theoretical force when 478 N load is applied I
