AbstractIn this study, a painted beehive panel from the collection of the Slovene Ethnographic Museum was examined with respect to its material composition with the aim to reveal the painting technique. Due to the state of degradation due to outdoor weathering (UV irradiation, rainfall, extreme temperature and humidity fluctuations), as well as past conservation interventions, the object represented a complex analytical challenge. We aimed for non-invasive techniques (FTIR in reflection mode, Raman spectroscopy and hyperspectral imaging in the range of 400–2500 nm); however, in order to explore paint layers, cross-sections were also analysed using Raman spectroscopy. FTIR spectroscopy in transmission mode and gas chromatography coupled to mass spectrometry were also used on sample fragments. Various original materials were identified such as pigments and binders. The surface coating applied during conservation interventions was also characterised. Additionally, organic compounds were found (oxalate, carboxylate), representing transformation products. The potential use of Prussian blue as a background paint layer is discussed.

Load is to be transported from one location to other location with the help of heavy vehicles, the load is placed on heavy vehicles with the help of crane or forklifts or conveyer belt, crane hook which bears the entire load. The weight of the load is related to dimensions and material of the hook.  The major part which is to be replaced as per load is crane hook, hook is subjected to pressure and bending stress. In the present work the crane hook of different cross sections is being analyzed on model of crane hook. The crane hook is modeled on the Solidworks and analysis using Ansys. From the structural analysis performed on crane hook the stress values based on the model and stress value modifications are found.
